When mahjong first caught on in America in the 1920's, the elegant sets imported from Shanghai looked like this: finely polished cases made from elm and rosewood and hand painted tiles made from cattle bone and bamboo. This set is a reproduction of those classic sets, crafted by hand from cattle bone and delicate slabs of native Chinese bamboo. The cover is inlaid with a bone design of birds and flowers. Please note that this is a hand made mahjong set made with natural materials using traditional methods. Each tile is cut and carved one piece a time, and the characters are inked by hand. Hand cut bone and bamboo tiles are slightly smaller than fiberglass mahjong tiles, and coloring and shape varies slightly from tile to tile and set to set.
