Aramith Premier Engraved Pool Balls are the highest quality pool balls available. Unlike screen printed balls where the colour and number are on the surface only the colour on phenolic engraved balls runs right through the ball and the number is part of the material. Perfectly round and balanced with uniform weight and hardness. These phenolic balls last up to five times longer than other balls made from polymers or polyester. With this durability they are the logical choice. Made in Belgium.s
