I've used it a few times, but it's in relatively good condition. I don't think there are any noticeable scratches, but please check the condition in the photos. Size: Approximately 20 cm tall Approximately 20 cm wide Approximately 9 cm deep (plus approximately 2 cm when expanded) Please forgive any errors as these measurements are approximate and taken by a layman with a measuring tape. It expands when you open the zipper. It's a small backpack, so please make sure it suits your needs.
