I'm selling this because my child has outgrown it. They liked it, but I don't think it was used very often. There's some fraying on the back and a little damage to the zipper decoration, but overall it's in good condition. Please refer to the photos for the size. There are no side pockets, so you can't put a water bottle in it... I plan to ship it via Takkyubin Compact, so I will compress it for shipping. #Odoruneko'sClothes Space Pattern Stars Planets Backpack
