I've been using this for about a year, but I'm selling it because I bought a new bag. As you can see in the photos, there are small scratches and marks from a ballpoint pen, but it's a very sturdy backpack, so I think it can still be used for a long time. (Please refer to the photos for scratches and stains) Please understand that this is a used item, so only those who are okay with that should purchase it.
