Office organizers and document managers, this Kokuyo Flat File is exactly what you need to keep your B5 documents neat and professional! The polypropylene (PP) cover is durable and protects your papers, while the resin binding mechanism securely holds up to 150 sheets with its reliable 2-hole design. The yellow color (catalog number H11Y) makes it easy to spot in your filing system, and the B5 size is perfect for those documents that are too big for standard binders but don't need full A4 size.
