Just another silicone cock ring? The silicone used in the The ROCCO Steele Hard ring is very unique, it is very soft and stretches incredibly easily. What makes it the best silicone ring on the market is that once stretched to put it on, it doesn`t snap back like most stretchy rings, it slowly retracts and provides a very comfortable amount of pressure up to 2.5x its size like it was made to the size you stretched it. The ROCCO Steele Hard is engineered with a fat flat band shape that ensures comfortable, but firm restriction, producing a hard as steel erection. Stretches to fit without binding. Because of the rings` stretchy, but firm material, just two sizes will fit most men. Inner Diameter: 1.75 in.
