M from MnK here!

I bought this ring because I needed a few bucks extra to receive free shipping on one of my orders. Oh boy am I glad I chose this over something else on the site!
The Ring O erection ring can be uses as a cock ring for solo play or sexual intercourse. Cock rings are used to help maintain an erection for a longer period of time, and in some cases they can prolong ejaculation. It will stretch enough to fit over the penis and testicles.

It's made out of TPR Silicone, which is a rubber/silicone mixture. It is also hypoallergenic, non-porous, latex and phthalates free. Also, you should only use water based lubricant. The ring is ultra smooth with nothing other than a little indent where the mold was injected (which is soft and unnoticeable). There isn't any smell from it.

The ring is nice and stretchy which makes it easy to put on. When I first opened the package and started to play with the ring, I was a little concerned that it wouldn’t work because of how easily it stretched. Since the inner diamater is only about 3/4" it was small enough to feel tight when stretched around the base of my penis. The ring is also super squishy which makes it very confortable when using.

Caring for this ring is very easy. Before and after use, wash it in warm water and antibacterial soap. I did notice that it picks up dust easily, so be sure to store it some place safe from the dust!

It comes in a little cellophane package. It reminded me of a giant condom wrapper! The instructions were written on the back of the package and simply said take out of package and put on penis.

Wearing the ring was a very nice experience! Because it is squishy, I can hardly feel it on the base of my penis and it doesn't interfere with intercourse. Even though I can't feel it, that doesn't mean the effects aren't noticeable. Within seconds after putting it on, my erection grew noticeably thicker and harder than normal size. While having it on, it was very easy to maintain a solid erection throughout.
