This is an onigiri (rice ball) pouch from BRUNCH BROTHER! The inside is aluminum, and there's a pocket for ice packs, etc. It's sturdy and cute. It seems to be a Korean character. Purchased at LOFT for 2100 yen + tax. Brand new with tags. At first glance, it might seem expensive, but I think it's not expensive for someone who uses it every day. A cute onigiri case with a cat face design, with a mesh pocket inside for convenience. - Design: Cat face design - Zipper: Gold zipper - Internal structure: Mesh pocket and aluminum lining Thank you for looking.
