Although I would not consider us to be "cock-ring connoisseurs" we do seem to have a fair number of styles tucked away in the nightstand drawers. As we never tried these exact ones, we figured what the heck! These appear to be your typical ring, although they seem a little thinner than others and less stretchy than some. Obviously easy to clean, and from tugging on them a bit, they do seem very strong.

The largest ring is about 2" in diameter, with each subsequent ring coming in just a bit smaller at 1.65" and 1.5". To put these on, first, apply a little bit of lube, then they should slide (or roll) right on.

Because these are not so stretchy, we found that although we could get them on the shaft, the idea of putting them around the balls and shaft was definitely not going to happen...they just aren't stretchy or big enough. We found we could get the larger ring near the base of the shaft with some effort and the middle size just to the middle of the shaft. The smaller ring was a struggle, but we could get it right over the head and no further.

Given the thinner size and lack of stretchiness, we figured these might dig in and hurt/pinch, but surprisingly they did not. In fact, they were comfortable to wear and stayed put during foreplay and intercourse.
