Rock Solid

Rock Solid is a cock ring brand with a few extras. Most of the range is silicone rings in named shapes such as The Donut, The Cog, The Tire and The Big O, alongside rubber gasket rings, snap-adjustable silicone and leather rings, beaded stamina rings, a lasso and a couple of ball stretchers.

Also here: a delay spray and an enhancing cream. Beginners should start with a stretchy or snap-adjustable ring and keep sessions short.
