This bag is designed to fit A4 size documents and features an expand function that widens the gusset when the central zipper is opened. It has high storage capacity, is sturdy, and very easy to use. I liked it, but I'm selling it because I have fewer opportunities to carry a lot of documents. Used for about 3 years, there is some wear and tear such as scuffing on the handles (see photo 3), but there is no major damage and it is still usable. Width: approx. 40cm, Height: approx. 30cm, Gusset: approx. 14-19cm (expand function) * The included organizer was discarded because I don't use it. Therefore, I am selling it at a low price. * Shipping will be on weekends due to work.
