Core Plug

(40 customer reviews)


SKU: N/A Category:


Core is the evolution of our highly praised Beta plug. It maintains all the same geometry that made Beta so comfortable, but adds a high-gloss surface which tends to be easier to clean. Core is made entirely of a soft medical-grade silicone that is bio-compatible and sterilizable, and it comes in three sizes:

The small is designed for intermediate users and eager beginners; the medium is designed for intermediate and advanced users; and the large is a treat for those looking for something more.

    Thank you for creating what I’ve been looking for….the Core Plug is perfect for my long term wear! I’ve tried many textiles and shapes over the years but nothing has been able to stand up to a 10-12 hour day as a busy restaurant manager on the move, this plug is perfect in every way for just that. Comfortable and no rubbing, completely invisible, and safely stays in place with a hectic work environment that includes heavy lifting as well. I’m now a happy gal and can get a lot closer to my long term wear goals now that I don’t have to interrupt it with not being able to plug while working.

    This is a fantastic product, no doubt about it. It was clearly designed by someone who enjoys using this sort of toy and knows what sort of features are comfortable. The base is great and the ratio between the flared bulb and the neck is perfect. Once it slides into place, it’s completely secure and you won’t need to worry about it slipping out at a strange moment. Even though this is a fairly large toy, I’m looking forward to the next size up!

    I stumbled across the “pluglove” site quite by accident, and it led me here. I knew I had found a kindred spirit — someone who had had the exact same experiences that I had with the Tantus Ryder plug. It has also been my “go to” plug for about 8 years, and I have been annoyed throughout this time with the way that its base flange digs in and irritates the external area. Internally, it’s great and fun to wear.

    So when I read that a guy who likes Tantus Ryder plugs but hates the irritation of the external base flange had designed a product that solved this problem, I knew I had to try this at once. I ordered both the Large and Medium units, and have been using the Medium one so far.

    The Core plug succeeds brilliantly. The base is absolutely, utterly comfortable — none of the chafing and irritation that is so common with other plugs (including the Ryder).

    The plug itself is also absolutely comfortable. In fact, it’s so comfortable that it’s possible to forget it’s there. I have held it up next to the Tantus Ryder plug, and the two appear very similar in size, EXCEPT that the distance between the back of the insertable part and the top of the base is slightly shorter in the Ryder. I believe this tends to keep the back of the inserted part pressed more strongly against the inner wall, making the presence of the plug more noticeable. I sort of like that effect, but not nearly enough to put up with the chafing and irritation of the Ryder. The Core plug is a definite winner.

    I noticed a very faint mold mark on the plug when cleaning it. It cannot be felt while wearing the plug. I am assuming it is not a serious issue and look forward to many enjoyable years using this plug. Anyone who wants a long-term wear plug will love this product.

    Just a quick addendum to my last post —

    After wearing a fairly squishy plug overnight and anticipating that it had opened me up adequately, I inserted the Large size Core plug this morning immediately after removing the other one. It took a bit of work but I got it in with no ill effects. I have to say that the Large plug is very lovely indeed, and unlike the Medium it is big enough to let you know it is there. Yet it is supremely comfortable. About the only thing I noticed is that if I sat down on a chair with a firm seat, there was sometimes a bit of internal poking from the tip of this plug . . . something the Medium never does. I think I may be extra sensitive to this kind of thing, but in any case it wasn’t really a problem. I anticipate that I will wear this at night, sleeping in bed, where such issues will not arise.

    And to answer the other question undoubtedly burning: Yes, it is possible to pass gas with this plug in place, just as it is with the Medium plug. This sets it apart from the squishy plug I mentioned, which creates a hermetic seal at the opening.

    Anyway, I still can’t believe it has taken this long for someone to design plugs that are this comfortable. I wish the best of success for these products.

    I just want to add one minor additional note that affects both the Medium and Large plugs. For some reason, even though the silicone surface is shiny smooth and seems to cleanup well with soap and water, there is a lingering smell (from where the plug was recently inserted) that persists despite thorough cleaning. It can be counteracted somewhat with a scented body wash such as Axe Excite or Dark Temptation. The Tantus plugs I own do not do this. I can’t tell any difference looking at them or feeling the surface — both are very smooth — but the difference is there.

    This is not a big deal. I just thought I should mention it. It does not affect my enjoyment of the plugs. And yes, I think everyone should own both sizes.

    I only have a few plugs but I was looking for the perfect one. I believe I have found it. The only thing I would suggest is, hopefully a Large to go with the Small and Medium options. I ordered the Medium Core, but if a Large were added to the site I would buy it without delay, so I would have something to work up to (or maybe replace with). Saying that, it does stay well in place. Not sure about the small, although I’m not interested in anything smaller than this.

    To anyone who may be wondering, even if you have hemorrhoids, this plug still sits very comfortably. I wore it the first time for several hours, and would have worn it longer but had forgotten to take my lube with me to work. I’ve re-inserted this morning and plan to keep it in for at least a few days.

    The plug itself is very smooth and has a slight give to it while still being firm. There is enough of a presence to this plug that you know it’s there, but it doesn’t have to be consistently on your mind if you need to focus on any other tasks, it slips your mind that it is even in. That’s how perfect the shape is. I am very glad that I found this site, and thanks for your hard work in creating it. 🙂

  7. Andrew (verified owner)

    WOW! This is the first plug I have been able to keep in for more than an hour or so. It’s just firm enough to let me know its up there. The very smooth surface makes it really comfortable to use with non silicone lubes such as elbow grease. The most important part is the external flange. It’s big enough to keep everything snug yet allow for all day wear including sitting down for extended periods. I’m getting longer and longer wear with this than any other plug I’ve tried. I just ordered the medium plug as I’m comfortable with the small model for longer periods of time. I LOVE THESE PLUGS!

  8. Anonymous (verified owner)

    Love the plug! Great for wearing while sleeping.

  9. John W (verified owner)

    If you’ve been searching for a plug for extended wear then you just found it. This plug is so insanely comfortable that I wear it all day and night. Even with water based lube I can sleep with this in and it’s still easy to take out 8 hours later with no pain. I’ve purchased every plug imaginable looking for something that is comfortable for extended wear and this is the one! I hope that they introduce a large version that has a slightly longer neck and larger base. Other than that this plug is perfect for everyday wear.

  10. Becca (verified owner)

    This is the best plug ever. I love longterm wearing and have struggled to find a plug most suitable for it. I’ve tried metal ones and while they were comfortable, the weight of them made it impossible to keep in long term out and about. I always wanted a silicone one with a comfortable flange for all day wear. This is it. I got to try this with a play mate and immediately asked him the brand so I could get my own.

    The medium size is so nice and filling but the design just keeps everything in place. I was pleasantly aware of it without feeling like it was in the way of living my life. And never once did it feel like it was going to fall out on me.

    I would also definitely get bigger sizes as they came out. 🙂

    (Yes, the plug does seem to hold on to smells. It’s something I’m willing to deal with because it’s otherwise exactly perfect.)

  11. Jaden

    Fits like a glove once I was able to get it in amazing I can use the bathroom and not worry about it falling out will have to carry lube around now for sure. I love how full I feel with it. Been awhile since I have owned a plug and am very pleased and so is my Mistress.

  12. Plug user

    LOVE IT, but there deffinately needs to be a larger version

  13. Analpluppen (verified owner)

    I love my medium sized core plug. It fills me up in a really nice way. Stimulates my sphincter and prostate for hours. At work and on my quality time. It almost feels like it is a part of me. But now my little assbuddy is dead. I was boiling it for desinfection and forgot about it until the firealarm woke me up. Not a nice smell and the plug was beyond rescue.
    So when i checked out the implicitcreations site i was very pleased that there was a new bigger plug. Have to get it. I have missed a little more stretch. Waiting for salary and will order the medium and large. Ordering to Sweden is about +40 bucks but have to have.

    Thanks Jim for your dedication!

  14. Criss

    I absolutely love my medium size Core plug! Took a bit of time working it in, but loved every minute! It is more comfortable than I imagined, and I can’t wait to start wearing it long term. Thank you for creating such a deliciously wonderful product!

  15. ET (verified owner)

    I have been looking for a comfortable plug for long term use. I saw a core plug review a few weeks ago. I went to the web store and ordered a large.. Just got it today…….. Wow! Snug fit won’t fall out. And comfortable.

  16. Analpluppen (verified owner)

    Got my Large core plug sooner than i expected. I love it. Bigger and more intense! Comfortable as always. Looking forward towards sleeping with it inside. Nice work Jim!

  17. Butterscotch (verified owner)

    This plug feels amazing! It is truly perfect! Thank you so much!!! I am going to enjoy this everywhere I go!!! And at home. Nothing like this!!!

    Stays in place. Totally discreet. Fabulous fullness and feel.

    I probably have about 12 plugs total. Getting rid of the others now!!

    Maybe one day I will graduate to the medium, but the small is perrrrfect right now.

  18. Matt

    The new large size is incredible; it’s what was missing from my collection! It falls perfectly in between the medium Core (leaves me wanting more at times) and the Tantus A-bomb (I get sore after a few hours). Like all the core plugs, it’s obscenely comfortable for all day wear. More advanced players can wear it forever without getting sore and still get that nice full feeling. Super secure during my day job and even workouts. My new favorite.

  19. Aaron (verified owner)

    I stumbled upon your plug review while I was doing a bit of research myself. Upon your suggestion, I bought the Tantus. Now, this was before you had decided to take matters into your own hands and create your own. I held off for a little bit but then bought the updated version. The medium was the largest size at that time. I fell in love! Then, you came out with the large. I must say, the first time I was able to work it in, it was astounding! Fantastic work, my friend!

  20. Eddie Nguyen (verified owner)

    Just got the large on 18-Nov.
    I plugged my self right after it arrived…..the feeling sooo amazing. fullness.

  21. Alexandra (verified owner)

    Just got Large today, this is best plug in the world! I couldn’t imagine better. I was looking for comfortable plug with thick neck for long time. Large one is just perfect for everyday stretching. I fallen in love since first time I used it, I wish I could never take it out 😉

  22. Eddie Nguyen (verified owner)

    I would like to add that I wear it for 24/7 without any problem.

  23. James (verified owner)

    Large plug feels larger than expected in a good way. It also stays cleaner than the medium one – go figure.

  24. RZimmermann

    I have had lots of plugs and dildoes and nonce as comfortable as this. I bought the large and have worn it on and off for a week now. I slept with it in a few nights and no issues. Great plug! I wear latex a lot when plugged and using silicone lube was a concern. I fixed that by using a 12″ latex balloon over the plug and then using Pjur BackDoor lube. Perfect fit!

  25. J (verified owner)

    I bought the small Core plug, and it is amazing! I have easily purchased half a dozen quality butt toys, and this is by far the most comfortable one I have encountered. The proportions, the tail that melts between your cheeks, the concave neck… all perfect for me. Despite the pointy appearance, the plug is very comfortable to sit on.

    I highly recommend using Coconut oil as lube; it is silicone-friendly and you can slather it on with abandon. For maximum comfort, be sure to lube the “tail” of the plug between your cheeks.

  26. Jeff

    I just recently got into plugs. Before this plug the largest one I tried was about the size of my finger so basically just a starter plug. Then I ordered the small which I’m wearing as I speak. Lately I’ve been craving a larger one so a medium should be arriving tomorrow when I have no doubt I’m probably going to go ahead and buy a large next week 🙂 this thing is supremely comfortable and even for a novice like me I’m wearing it 10 or 12 hours a day with no discomfort. occasionally if it begins to feel a little irritated I take a drop of lube and just run it around the outside of the handle around my sphincter and that slicks it right back up but that’s definitely not even required, just something I’m doing because I’m new to it. I can’t Say enough about how good this plug is. And oh my God orgasms with it in are amazing. Cant believe I waited so long to explore this type stuff!

  27. Polde (verified owner)

    I’ve had the medium and large Core for a few months now and have to say they are the most comfortable plugs I’ve worn (and I tried them all, all shapes and materials; metal, glass, silicone, wood, you name it). The advertised measurements are spot on, the firmness just right and shape is out of this world – easy in, easy out, stays put regardless of activty, fullness in the right places and the base that does not get in the way even when sitting long hours or hiking all day. Could not be happier! I wear them on no end – the medium at work and overnight, the large for evening home fun. I guess I found my buttplug nirvana!
    p.s.: There was a small issue with the medium Core, but Jim resolved it quickly and apropriately. Way to do business!

  28. Misha (verified owner)

    Ordered the large and it is as perfect a plug as I can imagine. Long term or overnight it feels wonderful.

    My only problem is the greed that makes me want an extra large to really challenge myself.

  29. Eddie Nguyen (verified owner)

    Highly recommended for long term plugging. I am wearing 24/7 now.

  30. B (verified owner)

    Amazing plug, had one for about two months now and I use it several times per week. Excellent shape, very comfortable, feels amazing. Even though I have the small, it’s still a very satisfying stretch and isn’t overbearing. It’s the toy I use the most, makes boring stuff like grocery shopping way more exciting. Orgasms are top notch. Great for long term wear, if it starts feeling dry after an hour or two just add a few drops of lube. Highly recommend.

  31. Ryan

    I received the small Core plug yesterday and couldn’t wait to try it out. For me, the small is larger than most other toys I tried, so it took some lube and patience, but once my body wrapped itself around the back end of the plug and it settled in, I hardly knew it was there. I have a desk job and I’m going to try to wear it for a couple hours today. Maybe even during my online staff meeting. They won’t even know but I’ll know what’s up. Thanks for a great product! I look forward to hours of happy use.

  32. Joaquin (verified owner)

    Best. Plug. Ever. I own dozen of plugs and have bought all of the most recommended brands, but this is just absolutely by far the most comfortable plug I have ever tried. I cannot recommend it enough. I would recommend the creator to make a size in between the large and the medium so add more variety, but that is all.

  33. Ryan (verified owner)

    I don’t normally leave reviews but I had to for this one. I started a few years back with the beta plug and absolutely fell in love with wearing a plug for extended periods of time. I was absolutely thrilled with the beta and couldn’t get enough of it. My only wish was for something larger and it came true. I recently ordered the large core plug and love it even more. I have been wearing it daily all day long and even slept on it some nights and love every minute of it. I absolutely love the large Core plug and can’t believe how comfortable it is to wear for 12 plus hours. Even my wife makes sure I don’t forget to put it in before work. She was so excited by it, she got one too. I am a huge advocate of their product and hope that more and more people support their high quality product. I will be a fan and customer of Implicit Creations for life and look forward to what’s next. I hope that one day they come out with even a larger size and you can bet I will be one of the first to order. Thank you for such and incredible product and first class customer service.

    Finally a plug that actually stays where it is supposed to be!
    I am currently wearing a size medium and cannot wait to move up to the large which I already purchased but found to be a bit too large.

  35. Jay (verified owner)

    This is seriously the plug I’ve been looking for! I’ve been constantly searching for the ultimate butt plug since I started daily wearing, I bumped into Implicit Creations on accident and loved the idea of a butt plug enthusiast designing and marketing their own. For years my go to has been the Fun Factory Boosty Large, but the base is wide and gets uncomfortable after a few hours, I upgraded to the Njoy 2.0 and thought it couldn’t get any better than that. Ive worn that one everywhere, including work and have set my personal best record (a week) of constant wearing. Only problem with the Njoy was, again, the base started to wear me out after awhile. Finally bit the bullet on the Core Large and oh my lord is this thing incredible! I, arrogantly, thought that since I can go all day with the Njoy that I could easily take on the Large. Was I wrong! Once it was in it became a whole other world and honestly the best fitting plug I have ever used. The base is so comfortable and tapered so gentle it allows you to sit down without a second thought (I would have to be careful with other plugs) I cant wait to give it a spin at work tomorrow, I’m a little worried the Large might be too big for all day wear at the office, if thats the case, Ill have to just get the Medium!

    One review in Swedish and one in English.

    Om du ska köpa nån butt plug alls köp dessa. Lite dyrare men så jävla mycket skönare än andra dussinpluggar jag haft.
    Beställde en medium och en large och med frakt, deklarering och moms betalade jag 1450 kr för 2 riktiga lyxpluggar. Med USPS och Postnord tog det 20 dagar innan jag kunde hämta ut paketet. För länge, men den som väntar på något gott…
    Grejen med dessa är att de är så sköna att ha i röven. Gärna länge! Har sexat, sovit, cyklat, jobbat, tränat, handlat och onanerat med dessa kåtpluggar och jag bara älskar dem! De glider lätt in och ut och sitter otroligt bra på plats och väl inne så blir jag härligt uppfylld, särskilt med den stora. Använder vattenbaserat glid eller kokosfett till mina. Funkar fint!

    Just hoping more swedes and europeans discover this butt treasure. Well worth the money. Thanks Jim for the toll declaration and your dedication in making this fantastic products for us butt lovers.

  37. Brooke Kaecker

    Absolutely amazing. I sleep with it in me most nights and even to work a couple times a week. Brooke Kaecker approved +++++

  38. Brooke Kaecker

    The large plug is simply amazing. Gives my butt hole a good wide stretch and it’s super comfortable. Stays in place all day. Can’t wait for the bigger ones to come out. Recommend to any and all anal lovers. Brooke Kaecker approved!!! A+++++

  39. Thefan

    I do O/F mostly extreme stretching stuff so the core large is basically my daily 24/7 wearable plug. I pretty much wear it all day to keep everything tuned up for the show if you get my drift and this plug is so comfortable for long term wear. I have not found anything that beats it. Once it’s in place it stays in place and the design of the base is smooth and very comfortable and gives that little something extra when you sit down. Honestly after you get used to butt play this plug is so comfortable you can actually forget it’s even there which leads me to my only complaint I wish they made a larger size. If you just have basic experience with buttplugs you’re probably going to want the medium but if you have some more experience you’re going to want the large size definitely. I also have to discontinued beta which was a awesome starter plug

  40. Thefan

    Just wanted to say is a perfect example of a company picking one thing and making the product to perfection
