OptiMale Supreme Pump
A manual pump designed for easy one-handed operation, puts the power to maximize your manhood in your hands. A clear cylinder with an imprinted ruler optimizes your view as you get harder and thicker, while a built-in pressure gauge at the top lets you keep an eye on every new development. When you’ve had enough, removing the pump is simple with a quick-release valve that lets you stop suction safely and quickly. This pump requires no batteries or electricity to operate.
