I made a mini-sized lunch bag using cute Scandinavian-style floral fabric and thermal insulation fabric for crafts. (Photos are for reference only. The lunch box and chopsticks are not included.) It's convenient for carrying things like rice balls, ice packs, and frozen jelly. It can be washed. This is a handmade item by an amateur. Please understand this before purchasing.
