This is an Offtoco backpack from Elecom. The exterior is gray, and the interior is orange. There are signs of use and some dirt. The dirt is a black scuff mark on the bottom of the bag, as shown in photo 5. Otherwise, I think there are no noticeable stains, including on the inside. I've used it for a while, so there's a general feeling of use. I don't think there are any functional problems. I will be listing it at a low price. I hope someone who wants to try it out will use it. When shipping, I plan to make some effort, such as folding it, to make it as small as possible. Please forgive any creases or folds that may occur during packaging. Thank you. - Color: Gray - Style: Backpack - Features: With front pocket - Straps: Adjustable shoulder straps - Material: Nylon Thank you for looking.
