The A4 envelope-style document pouch with transparent gusset (ref. 90761) stands out for its expandable capacity, designed for bulky files. Made of high-density transparent polypropylene with an expandable side gusset, it allows you to store a large number of A4 sheets without deforming the pouch. The Velcro closure ensures firm retention even at maximum capacity. The clear transparency allows you to see the first page immediately. It is the perfect choice for storing dense reports, legal documents, and sales catalogs.
