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.
