Pokemon 2-Tier Picnic Bento Box 1250ml with Belt This is a 2-tier Pokemon bento box. It's made of plastic and is a convenient size for sports days and picnics. The size is 12.5 x 12.5 x 5 cm (height when the lid is open) for each of the two tiers. It has been used only a few times, with little use, and has no noticeable stains. Thank you for looking.
