This rechargeable vibrating double penis ring helps you achieve firmer erections so you stay harder, longer. This uniquely designed double c-ring is made of stretchy silicone for a one-size-fits-all. The smaller ring slips around the shaft and the larger one around the testicles, which may help reduce premature ejaculation. The 10 vibration modes and super powerful motor offers lots of pleasurable possibilities for both partners. Completely submersible, this penis ring is the perfect companion for water play. Includes a travel-lock option and USB Charging cord.
