Satisfyer is thrilled to introduce the Duo line of double vibrating penis rings, designed with a ring to secure and stimulate both the shaft and testicles. Ideal for enhancing and maintaining erections while intensifying and prolonging pleasure, our Duo collection will exceed expectations. Each Duo features a powerful motor that delivers vibrations through the silicone bands and motor head, simultaneously stimulating your partner during penetration. The Legendary Duo has a thinner, slightly curved head and is available in Black. Its loops are thick with a flattened interior. The one-touch power button is elegantly integrated into a metallic detail on the vibrating head. - Body-friendly silicone - Rechargeable - Waterproof IPX7
