Heavyweight sheet protectors offer the solution to keeping your important papers protected. Designed both to protect your papers and 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 and durability to deliver protection that lasts. Acid-free, archival-safe polypropylene ensures your pages stay in top condition and 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 and 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 and protects letter-size papers.Heavyweight sheet protectors offer the solution to keeping your important papers protected.
