Very old mahjong tiles. As you can see in the photos, those familiar with mahjong will recognize these as high-quality materials and exceptionally beautiful tiles. The size of each tile is 24.5 x 18 x 14 mm. Because the carvings on each tile are subtly different, I believe they were all hand-carved by artisans. They have a solid weight, and the sound they make when handled is very refined and wonderful. These are for "antique collectors" and "connoisseurs who collect old mahjong tiles." Those who know, will know.
