Heavyweight sheet protectors offer the solution to keeping your important papers protected. Designed both to protect your papers & show them off impressively, Diamond-clear material delivers a crisp view of your pages as well as durable protection. Heavy material is designed for both premium feel & durability to deliver protection that lasts. Acid-free, archival-safe polypropylene ensures your pages stay in top condition & that print remains on your papers, rather than transferring to the sheet protector. The protectors' clear binding edge rounds out the professional look of your presentations & other documents. Easy Load feature provides a wider top opening so papers slide easily into place. Each three-hole punched page holds one sheet of paper & protects letter-size papers.
