TUMI ALPHA BRAVO DOVER Backpack for sale. I purchased this about three and a half years ago and used it for commuting. While there is a sense of use, there are no broken zippers or tears, and I believe there are no problems with its use. It's a versatile backpack that can be used for both business and personal use. Color: Black Size: Width: 30cm, Height: 42cm, Depth: 9cm *Please note that there may be some errors due to amateur measurements. If you have any concerns, please feel free to comment. Thank you.
