DUO rings are a hünkyjunk original - we made a chain-link style set of interlocked rings designed to wrap around your cock/balls, for "hunkier junk”! These super-rubbery silicone blend rings are smooth and soft when used as a double c-ring without being too tight. We made ‘em feel right! Or, flip one ring down to grip your ballsack…it’s all connected so any movement transmits from the base of your shaft to your ballsack--each ring is a different size, you can stretch and fit so many ways. The plus+silicone TPR/silicone blend feels smooth and warm…velvety like silicone + strong and stretchy like TPR. Hünkyjunk’s goal is to innovate—cool toys that fit and feel amazing--DUO is pure hünkyjunk, its Hüj!
