If you’re a fan of Oxballs’ best-selling AIR ring, you’ll love our newest ballstretcher version, AIRBALLS. AIRBALLS is made from soft, smooth plus+SILICONE blend so it’s stretchy and sleek but firm enough to give you that solid stretch. AIRBALLS has multiple drainage holes that make for lighter wear and double as holders for electro contacts. The ergo dip design and soft material make AIRBALLS great for high and tight sacks or for stacking with your favorite stretcher.
