Buy ivory billiard balls here. Ivory is no longer used in the production of pool balls(or at least at a much slower pace). The reason being overkilling of elephants in certain African countries. Today one uses synthetic substitutes. These balls are rare, and probably will become even more rare, due to the fact that this material is no longer used in the production(as it seems). It could be a good investment.
