What are the recommended procedures to follow in preserving these types of trophies?

Elephant, Hippo and Wart Hog tusks?

Elephant hair bracelets?

Lion and Leopard claws?

My Elephant hair bracelet I wear in the shower occasiionally. Like any hair, it tends to dry out. I have also used mineral oil on the bracelet and also on warthog tusks. I live in the high desert, so everything is dry.

Mike,

I coated my tusks and the teeth on lion and leopard skulls with clear epoxy. Totally stopped the cracking and looks great.

Ele bracklets...don't do a thing with them.
