This is a small, wooden lunch box. It has two tiers and a lid, with each tier holding exactly 200ml, for a total of 400ml. You can put rice in the bottom tier and side dishes in the top tier, and it looks great when you arrange them before eating. I used it a few times when I was dieting. There are no noticeable stains or scratches. It can be washed normally with detergent. I'm using a slightly larger one now, so would anyone like it?
