To see pictures of what kind of results you can get from ball pumping click here! Two stage tubes are intended for the advanced pumper who is doing both his penis and testicles. The design has a smaller opening at the base going into a larger cylinder. This allows the usera more comfortable size opening without sucking in more of the lower body - yet allowing plentyof room for expansion. Using this type of tube some men have pumped up their penises to 14" incircumference and their testicles to 24" in circumference. These tubes are expensive because they require up to 3 weeks to manufacture in some cases. Important: if you would like to order a two-stage and are not sure of what size to get, provide your measurments and we can help you choose the appropriate size.
