Clear sheet protectors offer tip-top protection for your documents with excellent clarity, security and strength. Convenient top flap prevents documents from slipping out of the sleeve so you can store papers in nonstandard sizes with confidence. Super-heavyweight polypropylene withstands frequent use in your binder. Acid-free, archival-safe design won't lift print and provides long-term protection. Sheet protectors are designed for storing papers up to 8-1/2" x 11".
