Baby & Kids Minions backpack and hat set. The backpack size is as follows: Height: Approximately 25 cm Width: Approximately 19 cm Depth: Approximately 6 cm Shoulder strap: Approximately 45 cm at its longest (adjustable) *Please note that there may be slight variations due to manual measurement. The backpack has a soft, velvety feel. There are no major scratches or stains. The child used it a few times indoors. It's for children, so the depth is narrow. It seems like it can hold a child's diapers, toys, and small picture books. How about it for a walk or going out? I may have overlooked something, so I'll sell it at a low price.
