Sometimes refered to as the "Measles Ball", The Super Aramith Pro Cup Cue Ball is one of the most sought-after items in billiards today! This ball has six red dots on its surface. One advantage of the red dot cue ball is that it makes it easy to "visualize the rotation" of the ball. You instantly see any inconsistencies in your shot. The ball is regulation 2-1/4" in diameter and is regulation weight.
