For several decades, Belgian Aramith Billiard balls have a legendary reputation for outstanding endurance and uncompromised quality. Used by almost 80% of the players worldwide, they are recognized as the reference of the industry. While less wear-resistant than the Super Aramith sets, the Aramith Premier sets still offers a lifetime up to 5 times longer than the other materials. Each ball is controlled along 7 criteria: density, balance, diameter tolerance, sphericity, color, surface polish and brilliance. All numbers are engraved to very tight specifications.
