This is the komabako (chess piece box) that came with the Moriage koma (raised chess pieces) I purchased. Due to the characteristics of the wood, I believe it is Japanese zelkova (keyaki), but I cannot say for certain. It's a high-quality box with a beautiful luster, and I think it's a luxurious komabako that you will cherish. Size of the top lid: 10.9cm (length) x 10.9cm (width) x 6.3cm (height) It's in beautiful condition with no noticeable scratches.
