The set includes 7 red balls, 7 yellow balls, 1 black 8-ball, and 1 white cue ball.
They are typically made from a high-quality, durable phenolic resin that resists chipping and cracking.
These balls are commonly used for playing 8-ball pool on UK-style pool tables.
The standard size for the object balls is 2 inches, while the cue ball is often 1 7/8 inches, especially for use in coin-operated tables.
