This is a collaboration product between DADWAY and DOD. It can be used as a baby backpack, as well as a pouch for small items or a shoulder bag. It's been used very little since opening, but the shoulder strap was lost during storage, so it's now a 2-way bag. I apologize for this. Please purchase only if you understand this point. Please purchase only if you understand that this item has been stored at home and has been inspected by a non-professional.
