I'm selling this because I no longer use it. There's a zipper on the side, so it seems like you can put something inside. The front pocket has a hook on one side, so you can attach something. It comes with a shoulder strap. Measurements (approximate): Depth 20 cm, Width 34 cm, Height 28 cm. Due to the thickness, it will be compressed and packaged minimally in a bag. Please understand. Color: White系 (White-based) Features: Has a depth/gusset Stains/Tears: Yes
