For a quick fix, vacuum cylinders enlarge your penis by drawing the blood into it giving you the biggest erection you've ever had! Start with a small cylinder then work your way up as you grow... The sensation as you draw the air out of the cylinder is unique, and many guys find the sensation so pleasurable that vacuum pumping clubs have started to spring up! It has become the ultimate in safe sex, and can be enjoyed on your own, with a partner or in a group. The side benefit of prolonged (but careful) use is an increase in length and girth. All you need to do is use a little lube around the base to get a tight seal - and start pumping away!

Each cylinder is made of the finest, medical-grade, industrial strength, clear acrylic. Each cylinder contains a state-of-the-art air valve which allows for quick and easy disconnection from the pump while maintaining pressure within the cylinder.
