Rock Solid Solid Cog Blue Glow

Bolt Shape and Fit

Smooth, stretchy hybrid silicone gives this chunky hex-bolt cock ring from Doc Johnson Novelties a soft feel that also glows blue in the dark. The stretchy inner opening and blue-glowing bolt styling give it a playful, industrial look with a bit of after-dark flair.

The bolt design is more than a gimmick. The thick outer body gives your fingers something solid to grip when sliding it on, while the 0.75" inner opening stretches to fit and then settles back into shape.

Design & Build

The ring is made from Sila-Flex, Doc Johnson's phthalate-free hybrid silicone. It has an ultra smooth, soft finish that feels pleasant against skin, and it is unscented, so there is no rubbery smell when you take it out of the drawer. The material offers extra stretch for an easier fit, and it holds its original shape after repeated use. It is also built to be durable, which matters for a ring that gets stretched every time you put it on.

The Glow Effect

The blue tint is only half the story. To charge the glow, hold the ring under a bright light or leave it in sunlight before use. Once the lights go down, it gives off a soft blue glow, making it easy to find in a dark room and adding a fun visual element to the moment. The effect fades over time, so a quick recharge under a lamp brings it back.

Care & Compatibility

Pair this cock ring only with water-based lubricant, since other formulas are not recommended for this material. A little lube on the inside of the ring also helps it roll on smoothly. After use, wash it with anti-bacterial soap and warm water, rinse thoroughly and let it air dry before storing. Keeping it clean and dry between sessions helps the smooth finish stay that way.
