These are bamboo-backed mahjong tiles. They are old, but do not hinder gameplay. The feel when holding them, and the sensation when the tiles hit each other, is pleasant. They have a retro feel, and there is no soiling on the glued parts that is characteristic of bamboo tiles. They come with a case, but the metal parts have rust and other deterioration. They are old, used items. Please check the photos and consider them after you are satisfied. The case in the photos will be simply packaged for shipping.
