Vacuum penis pumps are used for penis enlargement adding length and girth. A penis pump can be used as a masturbation tool. They can help a man learn to maintain an erection for a long period of time. Erections can be easier to achieve since the blood has learnt how to quickly flow to the penis. If we do not have these in stock (we will tell you) you may have to wait some extra time. Otherwise you may wish to take our deal....If we ain't got your pump in stock choose another and we will whack a few bucks off for your inconvenience.
