The OKKO Magnetic Billiard Cue Ball 2-Pack is designed for use on coin-operated pool tables equipped with magnetic ball return systems. Each cue ball features a built-in magnetic core that activates the table's ball separation mechanism, allowing the cue ball to be recognized and returned properly after play. Manufactured from durable Grade A polyester resin, these regulation-size cue balls provide reliable performance, consistent roll characteristics, and long service life. Precision manufacturing helps maintain excellent roundness, balance, and weight consistency for predictable cue ball action and accurate play. This convenient 2-pack is ideal for bars, game rooms, pool halls, recreational facilities, and home players who want a spare cue ball readily available. The durable polished finish resists wear while delivering excellent playability and value. Specifications: Brand: OKKO. Quantity: 2 Magnetic Cue Balls. Ball Diameter: 2-1/4" (57.2 mm).
