COG rubbery c-rings, 1 small + 1 large ring – the big COG is designed for guys that like a heftier super-stretchy c-ring, the smaller COG for a tighter fit, or wear it on your ballsack. Hünkyjunk likes to offer more options for all kinds of play. Each pack has 2 different color rings, both with knurled grip surface texture that looks cool and feels amazing… hünkyjunk loves the details! A groove inside the ring holds a bit of lube for comfortable wear and the inner ring flattens as COG stretches so the toy stays where you put it…it will not roll or pinch. The plus+silicone TPR/silicone blend feels smooth and warm…velvety like silicone + strong and stretchy like TPR. COG rings fit you many ways–hünkyjunk gives you more ways to play. Be Hüj!
