Used about 3 times. I am selling it because I was transferred and no longer have business trips. The shoulder strap is unused, and I don't know where to attach it. Key included. There are scratches on the bottom and the plastic part on the back. Please check the photos. It has a large storage capacity and many pockets, making it very convenient. The handle can be stored inside the zipper, and you can open and extend it when using it. Size: Width 42cm x Depth 21cm (including front pocket) x Height 35cm
