The Vulcan Vibrating Tight Mouth masturbator is made from Refined Touch, a realistic material that simulates the textures of flesh and skin. The top of this model is formed into the shape of lips, and the jelly material is clear. The internal length is five inches, with a 0.75-inch diameter. The device is contained within a discreet case with its own lid. At the base of the case is a small hole (covered temporarily by a security sticker) that the user can cover with a fingertip to vary the amount of suction. The device is easy to clean for multiple uses. It is waterproof and submersible and does not contain latex or phthalates. This vibrating model uses a removable push-button bullet vibrator with one speed and five patterns. It is powered by an N battery.
