Duo-layered with poly cotton, hand-stitched and double-reinforced using nothing but authentic cowhide leather; the only way RDX Sports knows how to build Patent Pending double end speedballs. Increase precision and head movement by using attaching the precision ball's heavy-duty nylon strap & rubber bungee cord that is adjustable up to 48 inches in height, and attach one end to the floor, and the other to the ceiling using the four high-quality metal S-rings and tough PVC buckles. The result is an all-angle precision ball that returns back to its position, regardless of the angle it was punched in. Watch your hand-to-eye coordination increase exponentially.
