Color: Black Many backpacks are square, but this one has a slanted top flap, giving it a neat appearance. I think it's suitable for junior high school students. When my son entered high school, he bought a square backpack, so I'm listing this in case any junior high school student can use it. My son used it for a year and a half for school and club activities. I washed it in the washing machine this time. I don't think there's any sand, but there are some frays and pilling. However, it can still be used. There's a hook around the chest area to prevent it from slipping down, and there are also pockets. Because it's large, shipping costs will be incurred, but it's included in the price. Thank you.
