Pool Balls

Billiard balls (Pool Balls) presently are made of synthetic plastics (polymers). This wasn't always the case as Pool Balls were originally made of Ivory. Ivory was in dwindling supply at and around the mid 1800's. Because Billiards had become one of America's favorite pastimes, elephants were being slaughtered to keep up with the demand for ivory pool balls.

Pool Balls usually come in sets and the quantity varies depending upon what pool game the balls are for.
