Sheet protectors are widely used as a tool to keep documents in their original condition. Once inserted into the holder, the documents instantly have a plastic, protective cover, which will help eliminate damage and tearing while they are being stored. Traditional Sheet Protectors are open on three sides, but documents are secured by a fold-over along the binding edge. The document holder includes black mounting paper for a more professional look. Polypropylene sheet protector is three-hole punched and won't crack, scratch or tear. Acid-free material eliminates 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.Package Includes: (50) Sheets of Black Mounting Paper
