Please note that I will be away overseas for a while, so shipping will be after the end of November. Columbia black backpack with padded back panel and adjustable straps. This item is attractive for its high storage capacity with a variety of pockets. It also has an externally accessible PC sleeve. It is suitable for town use such as commuting to work or school, as well as business trips/travel. - Brand: Columbia - Color: Black - Design: Padded back panel - Features: Adjustable straps Size (measured by an amateur) 51cm ✖️ 30cm ✖️ 18cm I think it's about 21-25L. Thank you for viewing. I have used it about 8 times. There is also an anti-theft pocket on the back. The photos look gray due to the reflection of light, but the actual color is black. There are some scratches and stains, but the zipper opens and closes without any problems, and I think it can still be used. I will ship it in simple packaging. Please note that there may be wrinkles. Thank you. Columbia Color: Black Accessories: None Stains/tears: Yes
