I have kept this for a long time. Overall, the condition is very clean! However, as shown in the sixth photo, there was a part where a piece was broken, so I marked it as "has scratches and dirt." By the way, it was possible to attach and detach the missing part. It has a large capacity and a zipper, making it convenient for organizing storage. Because it's box-shaped, it protects the corners of textbooks and documents, and I think it's a good backpack for high school students, students who carry a lot of things, and working adults. Please refer to the following for the size. (Please excuse my amateur measurements) ▽Dimensions on the back Length (height): Approximately 50cm Width: 30cm ▽Dimensions at the bottom Thickness: 14.5cm Please feel free to ask if you have any other questions. I'm waiting for your comments.
