Aer flight pack black Model number: AER21002 I bought this about 7 or 8 years ago when I first started working, but it's been mostly stored in a closet for the last 5 years. I didn't use it daily when I first bought it, and there are no noticeable stains or scratches, but there is some peeling on some of the metal hardware (see photo 4). The included shoulder strap is unused (see photo 8). I will ship it inside the backpack. Please understand that this is a used item. I am not accepting price negotiations.
