This is a convenient backpack organizer. I used it once when my child went on a field trip, so I marked it as "no noticeable scratches or stains." My child said it kept their belongings organized and made it easy to take things in and out. After that, the coronavirus pandemic hit, and I haven't had a chance to use it since, so I'm putting it up for sale. Outer material: Nylon Storage size: B5 size compatible [Large capacity] A bag-in-bag with a wide gusset for plenty of storage! A backpack organizer perfect for carrying tablets! [Various pockets on the outside and inside] The pockets, adopted from a monitor survey, are designed to neatly store small items of various sizes. ●Please note This item has been stored at home by a private individual, so please understand that it is a used item before purchasing.
