These skulls were all hand carved from a water buffalo bone. Incredibly detailed for a hand carving. The skulls are about 3/4" - 1" in height and about 1/2" - 3/4" in width. The skulls are all highly polished and drilled to be strung on a necklace. Each purchase is for 1 piece, purchase as many as you need. These make a great and unique gift.
