Mayan-style chessboard, stone-made

I purchased this item over 20 years ago during a trip to Mexico for approximately 20,000 yen. I bought it because I liked its appearance, but it has remained unused and stored at home ever since. At the time, the shop assistant explained that it was made of stone (though I've forgotten the exact type of stone) and hand-carved.I'm selling it due to an upcoming move. While it's unused, please be aware that it's been in storage for a long time, so please refrain from purchasing if you are particularly meticulous.Size: Approximately 17cm x 17cmNumber of pieces: 16 pieces x 2 sets outstanding for everyday use. finest materials and excellent craftsmanship ensure long-lasting durability.
