This is "Shagai," used in traditional Mongolian fortune-telling and games. Shagai refers to the ankle bones of livestock such as sheep, and has been treasured in Mongolia since ancient times as amulets, game pieces, and fortune-telling tools. Shagai has four sides, each representing a different animal: "Horse, Camel, Sheep, and Goat." You can tell your fortune based on the sides that land face up, and you can also play games using all four sides! They are small and cute, and are also recommended as interior decorations or amulets. How to Play/Use: Fortune-telling: Toss them and see the combination of sides that land face up to tell your fortune (with an explanation of results in Mongolian).
