Satisfyer is excited to launch our line of Duo ''double'' vibrating penis rings - each complete with a ring to secure and stimulate the shaft as well as the testicles. Perfect for strengthening and sustaining erections while heightening and delaying pleasure, our Duo line up will not disappoint. Each Duo is equipped with a powerful motor to transmit vibrations through the silicone bands and head of the motor, simultaneously arousing your partner during penetration. The Majestic Duo, available in Black, features one long, stretchy band that goes around both the shaft and testicles, or you can double loop the band around the shaft only. The flat, clickable button on the front of the motor makes it easy to control. All Duos are made of smooth, body-friendly silicone, are fully waterproof and complete with 12 powerful vibration settings. - Body friendly silicone - Rechargeable - Waterproof IPX7
