This is a mini nylon backpack that I received as a novelty item from Mister Donut. I used it a few times and then stored it folded for a long time. There are no pockets inside, but there is a zippered pocket on the front. The shoulder straps are adjustable, so it can be used by children and adults. Size: Approximately 20cm wide x 23cm high x 10cm deep (Please note that there may be some errors due to amateur measurements) The item will be folded and shipped. I soaked and washed it before listing it, and then dried it in the sun, so I think you can use it with confidence. Please understand that this is a used item before purchasing.
