Thank you for looking. This is a set of a 3-tier bento box and a cooler bag. It has been used about 2 times and is very clean. Disinfected with alcohol. How about for cherry blossom viewing or sports days? We appreciate your understanding of this being a used item and stored at home. Bento box size: 22cm (width) x 22cm (depth) x 18cm (height) for 3 tiers.
