This is a lacquered bento box with dividers, purchased approximately 20 years ago at Mitsukoshi Nihombashi. I didn't check the type of lacquer when I bought it, but it's a "Special Guarantee" (special quality guarantee) bento box with a beautiful vermilion interior and a wood grain finish. I've used it 3-4 times, and it has been stored at home since then. Upon close inspection of the lacquer on the upper lid, there are a few small, whitish spots that are barely visible in the images (see images NO. 12-14). Otherwise, there is no noticeable damage. I apologize, but I have forgotten the purchase price. Due to long-term home storage, the outer box has some dents, and the inside has discoloration and stains. Body exterior dimensions: 18cm x 18cm Lid exterior dimensions: 19cm x 19cm Outer box: 20cm x 20cm
