A soft ring at the base envelops the penis very delicately, interrupting access to oxygen and creating a vacuum effect, the air is pumped out using a convenient piston. The flask of the pump is made of durable and reliable ABS plastic, a clear pressure gauge displays the degree of pressure in the flask, and a dimensional ruler on the surface allows you to note the difference before and after massage. Regular massage pumping cleanses blood vessels, improving an erection. Black colour. Length: 20.0 cm. Width: 7.0 cm. Material: Silicone + ABS plastic.
