USB backpack. I'm selling this because I don't have a chance to use it. I used it a few times and then stored it in a dark place. I've blacked out the name tag. I may fold it up small for shipping. I'm also selling other bags. I'd like to sell this to someone who understands that it's a used item and has been stored at home. I'm new to Mercari, so I'm not considering lowering the price.
