This TUMI business bag is made of durable nylon material. It comes with a detachable shoulder strap. It can also be used as a backpack. It's expandable, so it can hold a lot of luggage. The tag has been removed, but is included. - Brand: TUMI - Color: Black - Style: Business Bag - Material: Nylon - Number of Pockets: Multiple - Handle Type: Double Handle Purchased 2 years ago. Used about twice a week, but it's in good condition because it was mainly used on top of a suitcase. Size: 28 x 40.5 x 12 (15 exp) Thank you for viewing. I am selling it because I bought a new bag. I am still considering whether to keep it myself, so I generally cannot offer a discount. Color: Black系 (Black-based) Accessories: Shoulder strap
