COG rubbery c-rings are 1 small + 1 large rings. 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…at hünkyjunk we love the details! FEATURES: Hünkyjunk innovation for COG: a groove inside the ring that holds a bit of lube for comfortable wear and a inner ring that flattens as COG stretches so the toy stays where you want it…it will not roll or pinch. Our plus+silicone™ TPR/silicone blend feels smooth and warm…velvety like silicone + strong and stretchy like TPR.
