Sterling's Carom Ball set consists of three 61.5 mm carom balls: one white, one red, and one yellow. The balls are a combination of unique craftsmanship and high-technology providing consistent superior quality. Perfectly round and balanced - uniform weight and hardness - brilliant colors - friction resistant roll and reaction - are just a few of the key features that have earned Sterling's solid reputation. Produced to the most exacting standards and tolerances, each ball is individually callipered to insure maximum consistency from ball to ball.
