This toy is designed to provide 3 different size cock rings in a set. A single cock ring should be slid down your penis to the base, which will reduce the ability of blood to flow back out... this should both increase size slightly but also help keep you harder longer potentially. Your mileage may vary... do not wear these rings or other cock rings for extended periods as these can have significantly negative health impacts, such as clotting, strokes, etc. if you do.

The toy is made out of a clear stretchy thermoplastic rubber (TPR). This toy material is a 7 on the EF safety scale. So can't be sterilized; however, it should only really be used externally so I'm less concerned about full sterilization of this toy compared to insertable toys.

The toy claims to be of a "Non-sticky" TPR; however, while it doesn't feel sticky to the touch it does have a lot of grip so when trying to put the ring on, it griped the skin on my penis and tried to pull it with it. This didn't feel pleasant. The solution is to stretch the ring farther so it didn't grip my skin as I slid the ring down to the base of my penis. There is a seam in the middle of the rings, both internally and externally from the mold that made them, which likely compounded the grip issue I noticed.

The toy has no real texture outside of having some grip to it, it is reasonably smooth. The ring doesn't really offer stimulation and the texture of the toy doesn't impact its functionality much one way or the other.

I like the fact that the toy designer realized that not all penis are the same size and provided 3 different sized rings in one package. My issue with this is that it's wasteful if you can't use two of the sizes. I'd rather spend more or less and get one ring that actually fits, than have two that don't sitting around gathering dust. Honestly, even the largest one didn't work for me and was still a bit too tight for my enjoyment; however, as I continue to discover I'm seemingly above average for penis size and many toys aren't designed to fit me.

The other nice thing about these rings are they have loops on either side, which provide a nice handle to stretch them for putting on or taking off.

The rings are are likely too small to fit over both shaft and testicles.
