It was convenient because it could hold balls, water bottles, and shoes all together, so my child didn't forget anything. I think it's clean because I took care of it, such as washing it with a neutral detergent. I looked at other items when listing this one, and I think the condition is quite good. It's a size that can be used from upper elementary school to high school students ^ ^ 。。。。。。。。。。。。。。 Nylon backpack in black, with adjustable shoulder straps and a front pocket. - Brand: molten - Color: Black - Style: Backpack - Strap Type: Adjustable shoulder straps - Features: With front pocket - Material: Nylon Thank you for looking.
