Thank you for viewing! This is a self-supporting commuter bag that can hold A4-size documents, tablets, and even a lunch box. It has many pockets and a long strap, so it can be worn over the shoulder. I think it's a very user-friendly product. I bought it a few years ago and used it a few times, then stored it in a bag. It has been used very few times and is in good condition. Width: Approximately 40 cm Height: Approximately 29 cm Depth: Approximately 12.5 cm Please consider purchasing if you understand that this is a used item and has been stored at home.
