The Esselte No. 1 A4 Lever Arch File in Grey is a professional-grade document management solution built for heavy-duty office use. Constructed with a rigid, high-quality board core and vacuum-wrapped in a hard-wearing polypropylene (PP) foil, this file offers a moisture-resistant and wipe-clean finish that resists scuffing. It features the patented No. 1 mechanism, engineered for superior locking force and consistently precise pin alignment for at least 10,000 uses. With a slim 50mm spine for space-saving storage, it includes metal-reinforced bottom edges and a secure Rado cover lock, ensuring the file remains stable and perfectly closed even when stored upright on a shelf.
