Calling a civil servant a "file monster" is another way of saying that he carries out his duty with exemplary expertise. We recommend this flexible document folder as a true "file monster" that can expand to become a file tower. A stepby-step retractable back hidden in the rear lid allows it to literally rise to the occasion. For documents, periodical volumes, and even enough space for several volumes of illustrated catalogues. In order to keep together what belongs together, the file is equipped with a linen strap and steel buckle.
