This ball stretcher allows you to test your limits. Start with a manageable tug by slipping the U portion of the stretcher onto your scrotum above your balls. Savor the pull of the heavy-duty stainless steel as gravity takes it toll. Two connector chains dangle with convenient hooks for adding weights (not included). The durable material is non-porous making it easy to sanitize after each use. Stretcher is 5.5 in. long. Chains are 9 in length. Opening for scrotum is 0.75 in.
