Hello and thanks for looking at this vintage Star Wars BB-8 backpack. It's about 17" x 17" and is in good used condition. The zippers work fine and there are no holes, stains or tears. Storage is one big cavern inside you can cram a lot of stuff in here. There's a small zipper pouch on the outside that's about the size of a pencil bag. Padded straps are adjustable. This backpack is for teens up to adults.
