Thank you for taking a look! (^-^) This is an insulated bag with a zipper. The exterior uses printed fabric and twill fabric. The lining is an insulated sheet (Toray's Sunstate AL), making it a small cooler bag. It can be used for things like onigiri (rice balls) or a small lunch box (^o^) Height: 15cm, Width: 19cm, Depth: 8cm There may be slight variations in size. Please confirm the size before purchasing (^-^) This item is washable, but please hand wash or use a laundry net when washing. It will be folded for shipping. As this is a handmade item, we appreciate your understanding. Thank you very much (^o^)
