Mayan Style Chess Set - Stone

Purchased in Mexico over 20 years ago for approximately 20,000 yen at the time.
I bought it because I liked the appearance, and then kept it stored at home without ever using it.
At the time, the store clerk explained that it was made of stone (I've forgotten the name of the material) and was hand-carved.

I am listing this item due to moving.
Although it is unused, please refrain from purchasing if you are sensitive about long-term storage items.

Size: Approx. 17cm x 17cm
Number of pieces: 16 pieces x 2 sets
