It is a complete set of 16 balls, including 7 red, 7 yellow, 1 black 8-ball, and 1 white cue ball.
The colored balls are typically 2 inches in diameter, while the cue ball is often a slightly smaller 1 7/8 inches for use in coin-operated tables.
The balls are made from durable polyester or phenolic resin, known for resistance to scratches and impacts.
They are checked for perfect roundness and consistent weight to ensure a true roll.
