Hishibon (Diamond-Shaped Tray) Urushi Lacquer Finish This is a black tray used in the tea ceremony to hold the tea caddy. It belonged to my mother, who practiced the tea ceremony. There doesn't seem to be any overall damage, but depending on the angle, there are marks from where the tea caddy was placed, as shown in the image. This is a USED item, so please understand this before purchasing.
