Get the stretch you crave one ring at a time with Ring Master Custom Ball Stretcher Kit from Master Series by XR Brands. Designed to satisfy your need for intensity, this 6-ring set tests your limits as you stack each stretchy band around your balls. Wear them all at once or one at a time, or wrap them separately around your testicles and shaft - the choice is yours with Ring Master. Beginner-friendly 6-ring stretching kit slows blood flow to the balls and/or cock for an erection that feels bigger and more sensitive. Keep your balls pulsing with increased sensitivity as you push your boundaries in performance with Master Series! Lubricate well with a favorite water-based lube to slide the bands in place, then clean up in a snap before and after use with antibacterial soap and a warm water rinse (air-dry completely prior to storage). Ring Master Custom Ball Stretchers are made with body-safe TPR for your peace of mind. Each hoop measures 1inch diameter (3 cm), unstretched, and come 6 hoops per pack.
