ULTRABALLS is the new and improved redesign of our best-selling POWERBALLS cockring. It's available in a convenient two pack to give you the most bang for your buck. ULTRABALLS is made from our FLEXtpr so it's soft and stretchy enough to fit men of all sizes. The rubbery balls on the underside push your package up and out and gently grip your junk for a harder, longer lasting erection.
