Short Stainless Steel Catheters Male Sound Dilator Inserts Plug for Men, 6 Sizes Optional G111 (11mm)

When purchasing this make sure you can accommodate the size you order. I went bigger than I usually wear and really had to stretch my internals of my shaft to alow it to enter in all the way. At first it seemed impossible to get all the way in but eventually did. Wish I went a bit smaller in width.

I've gotten to the point where 10mm is too small to stay in place, but 11 mm is still a little too big. The slight taper on this product made it possible for me to finally fit an 11 mm! It popped into place and stays in snug with very little discomfort.

Well made. Easy to use.

pop's in and stays put-works fine

I have purchased four of these so far and each has been excellent quality. The only downside is once you move up to the next size, the smaller ones become pretty useless.

I bought a 9mm and a 10mm. The 9mm is pretty much 9mm but the 10mm measures at 10.18mm at the widest point. They are also not very smooth, they look like the ring inside the end is rough and it is on both of them.

This is the first plug that stays in. Most are rubbed but the football shape helps keep it in place. Just the right amount of flow also. Comfortable about wear all day.

Pop it in and it pops back out, save your money.
