The thick jelly like rounded cock ring is a popular and common item in the world of cock rings. But Hunkyjunk have improved on the classic design with the Hunkyjunk Cog Ring 2 Pack. It's made from a super stretchy plus+silicone in an industrial style design that is going to give a great grip.
The Hunkyjunk Cog Ring 2 Pack contains two different sized thick chubby TPR / silicone blend cock rings that has a thick cog like design with idents on the outside and sides that are squared off rather than rounded. The beauty of this cock ring is that because it hasn't got rounded edges like a donut style ring it will stay in place with less roll. The inside also has a small groove inside it that flattens out to help keep the cock ring in place. This cock ring 2 pack has 2 different sized cock rings that can help you find the perfect fit or mix and match for cock and ball wear.
The smaller ring has an internal circumference of 2.75 inches, an external circumference of 6 inches and is 0.5 inches thick.
The larger ring has an internal circumference of 3.2 inches, an external circumference of 6.75 inches and 0.75 inches thick.
These cock rings are fairly easy to get on because of the amount of stretch they have. But the thickness of them makes them pretty solid. Just pop your manhood through the hole and then stretch it over your balls so that it sits nicely behind them close to your body. Or you might find it easier to put your balls through first and then stretch over your manhood. If placing the second ring on your balls stretch it open from underneath and pull your balls through using your hand to make sure it doesn't snap back on them.
Fitting Advice
