This is a sturdy box that was used to store kimono accessories. Inside the box, there are two smaller boxes, each half the height of the main box, creating a two-tiered storage system. Size: Approximately 40.5cm x 27.5cm x 13cm (height) I don't know the specifics, but the material appears to be thick cardboard, with a patterned vinyl tape-like coating on the surface. It's a very robust box. A plastic cover is also included. It has been stored at home for a long time, so there is some wear and tear on the corners, and the center of the lid is slightly warped. If anyone can make use of it, please feel free to take it.
