Centennial Premium Pocket Balls are the standard of excellence in the industry. Made with premium-grade phenolic resin, Centennial balls are ground and polished to exacting radial tolerances of 0.001 of an inch for absolutely true and accurate roll. Components are solid cast and “vitrified,” or heat fused, for a homogeneous molecular bond. A translucent ivory hue, lustrous color, and a unique “dart” identify Centennial® Balls. With resiliency and balance that allows hairline accuracy, and with numbers and colors that will not rub off, spot, or fade, Centennial® Balls are superior in both playing quality and appearance.
