Keep documents protected and in their original condition with C-Line® Polypropylene Sheet Protectors. Top-loading sleeves prevent crumpling, tearing and various forms of handling damage while providing an element of moisture-damage resistance; and as they're pre-punched, there's no sheet punching required if you wish to insert important documents into your binder. Once inserted into binders, their reinforced binding edge minimizes the potential for damage. Manufactured acid-free to prevent photocopy transfer. This product will be cheerfully replaced with one of equal value if defective in materials, manufacturing or packaging at the time of purchase.
