GRIP YOUR BALLS! - The Greaser Gripper resurfaces old, slippery lacrosse balls so they feel and play like new. No more throwing greasers and shiners into the woods. - SIMPLE TO USE: Place the Greaser Gripper into the chuck of your power drill (not included). While spinning the ball, apply LIGHT pressure with the abrasive pad as you move the pad back and forth. Each ball can be resurfaced many times.
