Diameter: Approximately 28cm Height: Approximately 4.5cm This is an old tray. There are stains and blemishes. Please be aware of this. I've been told it's from the Taisho to early Showa period. I don't know the type of wood, but it seems to be a very rare wood. Fine lines, like those drawn with a pen, are visible. In English, it was described as "spalted." It seems to be wood where fungi or mold have entered through damaged areas, creating black streaks and unique patterns within the wood. Among them, it seems rare to have so many fine lines intertwined like this. I read that it has been highly valued in foreign countries since ancient times. I think it's fascinating that someone used this wood to make an Obon tray in Japan; in the language of the time, wouldn't you say it was very stylish? The woven edge is delicate and carefully finished. My knowledge of wood is limited, so please judge based on the photos. I think it's very interesting from a historical perspective as well.
