Overview The Firefly Bubble Rings are a set of three glow-in-the-dark cock rings made from soft liquid silicone. They come in three sizes — small, medium, and large — so you can find a fit that actually works rather than forcing a one-size ring and hoping for the best. The silicone construction keeps things comfortable during wear, and the rings are designed to maintain firmness and heighten sensation during sex. Compatible with all lubricant types, including silicone-based. These rings come in three distinct sizes in the one pack. The small sits at 4 cm diameter, medium at 5 cm, and large at 6 cm — measure up before you commit to one, as the right fit makes a significant difference to how well a cock ring performs.
