Black backpack. Approximately 14 x 20 cm gusset, approximately 37 cm height. A backpack cover was attached to the top pocket, but I have never used it. There are no noticeable stains, and the inside is relatively clean, but since it's black, there are some whitish lines on the outside. I haven't used it very often, but I hope you understand. #SchoolCommute #Bag #Backpack #Black
