Enhancer Cockring 2 Pack features two silicone rings, one even with a bow tie for that black tie affair! Both rings are made from 100% soft, silky silicone and are very stretchy to accommodate a variety of penis sizes. The non-vibrating ring surrounds the base of the penis and separates the testicles. The vibrating ring features a removable bullet and small, stretchy connected butt plug. The vibrating cockring requires a AAA battery which is not included. For the best experience, please pair with a water-based lubricant and clean before and after each use with toy cleaner.
