GAKU W Washable Load-Reducing School Backpack is designed around the concept of a machine-washable hardcase backpack. It combines a 180-degree fully opening flat structure, removable support panels, anti-misopening zipper protection, color-matching labels, and a custom laundry bag, allowing the body to be washed in a household washing machine and completing the process from removal, washing, drying, to reinstallation.
