Pingu Kids Backpack Capacity: Approximately 8L Size: Approximately H305 x W240 x D110mm The back of the shoulder straps and the back panel are made of breathable mesh material. It's a cute Pingu backpack. It's light blue, so I think it can be used by both boys and girls. Although it is unused, please understand that it has been stored at home. There are folds and wrinkles on the tag. Shipping included.
