The part in the third photo is missing. If you need it, you can search for "backpack buckle" on Amazon, etc., and purchase one for around 500 yen. It's a strap for attaching to a stroller, so it's not a problem if you don't use it. Size (Width 31cm, Height 36cm, Main space depth 16.5cm, Shoulder strap width 6.5cm) *This item has black fabric, a silver zipper, and a black logo embroidery.
