This durable nylon business bag can also be used as a backpack. The shoulder straps can be stored inside the back panel, allowing it to be used like a business bag. When you have a lot of luggage, you can expand the bag by opening the outer zip. It can be used for everyday commuting and private use, as well as for short business trips and travel. A separately sold compression strap is also included as a bonus. I used it for about a year, but I stopped using it because I had less stuff for work, so I'm selling it. The magnetic key strap has significant plating剥がれ (peeling) on the metal parts. Other than that, there are no noticeable scratches, stains, or sweat marks, and I think it's in good condition. Please understand this before purchasing. - Color: Black - Style: Business bag - Features: Can also be used as a backpack - Material: Durable nylon - Straps: Adjustable shoulder straps Thank you for viewing.
