This is the bag that came with the Cinnamoroll kids' osechi (New Year's food) set I purchased a while ago. It's a square bag with a gusset, perfect for carrying lunch boxes or osechi boxes. There's a faint yellow stain in one area (see photo 7). It seems to have many uses, such as storage or a toy bag. I hope you can understand that this is a used item. Thank you.
