This textured vibrating silicone double ring offers two bands to wear around the testicles and at the base of the penis for larger, harder erections. The bottom portion of the ring rests perfectly behind the testicles to stimulate the perineum for incredible sensation. The 10 vibration modes create a new level of sensation for solo or partnered play. The 100% waterproof design allows for use while in the bath, shower, pool, lake... wherever getting wet happens.
