Simple leather cock ring (CR-15-BLA)

What could be simpler or better to use?

A simple 1.5cm wide leather ring with smooth metal popper-studs which adjust to between 15 and 21cms long; offering the wearer options as to how and where to use this ring.

This ring is great to use and is made of the softest leather for comfort; but the poppers hold the the ring closed very securely, ensuring that once on, it won't shift or open, despite a considerable amount of pressure.  What a find!
