This is a two-tiered black bento box that I used for three years in high school. It has some scratches and other signs of use, as it was used. Please purchase only if you understand this. Capacity: Top 400ml, Bottom 460ml (as stated on the product) Microwave safe. Please refer to the back of the product for heat resistance information. This item is also listed on other sites. The shipping method may be changed from Yu-Yu Mercari Bin to Raku-Raku Mercari Bin. I hope someone who needs it will use it.
