Alligator teeth are naturally hollow inside because they fit into the mouth of the alligator one inside of another 3 at a time. If one is dislodged, there is always another right underneath it. Despite being hollow, these alligator teeth are strong and durable teeth. These are approximately 1 1/2 to 1 3/4 inches long and have been predrilled for use as beads. Photos are stock photos showing typical teeth. Out of country buyers, my apologies but we cannot ship wildlife product outside of the United States.
