African elephants are often illegally hunted by poachers for their ivory tusks. Obviously, one way to help protect elephants is to never buy products made from ivory. But unlike intricately carved ivory tusks, statues and jewelry that are clearly made from ivory, there are many home items also made from ivory that aren't clearly marked. Things like billiard balls, dominos, fans, piano keys and carved collectibles can also be made from ivory. The easiest way to tell if an item is ivory (and not bone) is to run your fingers across it. If it's smooth like butter, it's likely ivory. If it has any texture or pockmarks, it's likely bone. When in doubt, move on.
