These are real North American buffalo teeth from bison, not water buffalo. The teeth were taken from ranch raised buffalo that were killed for meat. They have been cleaned, but are NOT drilled. They are ideal for making pendants. They can be stained in tea to make them look old fashioned. The teeth are approximately 1.5 - 1.75" (3.75 - 4.4 cm) long and 1/2" to 5/8" (1.25 - 1.5 cm) wide.
The teeth and molars come from ranch-raised buffalo and are a by-product of the food industry. The buffalo were not killed just for their teeth.
