Packaged and marketed to enhance men's private lives, Ringos are vibrating cock rings made of 100-percent pure platinum silicone, which makes them easy to clean. One blue and one black with varied flexibility — the blue one is the more forgiving of the two — Ringos come with a powerful bullet packing strong, single-speed vibration. Compatible with non-silicone-based lubricant, Ringos work best when combined, one around the shaft and the other around the testicles, for the strongest orgasms possible for the wearer and his partner.
