This is a black box-shaped bag (backpack). Due to its square shape, textbooks, notebooks, and reference books fit neatly into the corners, making it very easy to put things in and take them out. With a height of 40cm and a depth of 15.5cm, it's a size that can hold a lunch box, water bottle, and a change of clothes. I think it's a very easy-to-use design for commuting to school for junior high and high school students, or as a bag for cram school. 【Size】 ・Height: Approximately 40cm ・Width: Approximately 30cm ・Depth: Approximately 15.5cm *Please forgive any slight errors due to amateur measurements. 【Material】 ・Nylon (Black) This material is lightweight and doesn't easily show dirt. 【Condition】 This is a used item, but there are no noticeable stains or scratches, and it is in overall good condition.
