This is a nylon backpack from GU. I purchased it from the GU online store and used it about twice, but I'm selling it because I often use other backpacks. There are no major scratches or stains, but it is a used item, so please purchase it only if you understand that. I will fold it and ship it in a packing plastic bag. Due to caring for family at my parents' house from Wednesday to Friday, if purchased during that time, shipping will be on Friday night, so please be aware of this.
