Mark Gonzales What it isNt Mark Gonzales Rucksack Backpack Black Lightweight Large Capacity Commuting to School Street I used it a few times before, but there are no noticeable scratches or stains on the sides or inside! The zipper works fine. It has a 3-pocket structure with high storage capacity. It can store A4 size and even B4 size. It's a backpack that's easy to use and can even fit a laptop. It also has a D-hook, which is convenient for keychains, etc. Recommended for commuting to school with a lot of luggage! Size: H45 x W41 x D13 Material: 100% Polyester
