Thank you for viewing. This is a bentwood lunch box made of Akita cedar by Odate Kogei. I'm not sure when I purchased it, but it was quite a while ago. It has never been used. Additional note: Although it's not visible in the photos due to light reflection, there is a thin line along the curve of the lid's edge and a small indentation in one place. Also, the box is old, so please consider this before purchasing. Thank you very much.
