The Duo is a double vibrating c rings each with two loops; one to secure and stimulate the shaft and a second for the testicles.

If you are familiar with our c ring, then you already know how the sensual silicone bands wrap around the shaft to restrict blood flow in order to strengthen and sustain an erection. With the Duo line, a second loop was added to pull the testicles close to heighten and delay pleasure even longer. 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.

Features:

• Made of smooth, body friendly silicone
• Fully waterproof
• 12 powerful vibration settings
