Thank you for viewing. This is a child's backpack. It was a magazine supplement, but the size was too small, so it didn't suit my daughter who wanted to put a lot of things in it, and she didn't use it. The length is adjustable, so I think it can be used for a long time. My daughter put colored pencils directly inside, so there is some dirt, although it's in a place that can't be seen. When shipping, I will flatten it for mailing. If you can agree to this, please consider purchasing.
