These handy scuffers are great for shaping the tip perfectly every time and can be kept in your pocket or pool cue case for on-the-go tip maintenance. Shape and scuff your tip with a 1 square of aluminum with embedded carbide. One side shapes your cue tip to a perfect radius while the other scuffs the tip for optimum chalk retention. The cube shape makes it easy to hold and lightly sand the tip. The same motion that you use to chalk your tip is perfect for shaping it.
