Artists, photographers, and collectors - these clear bags are absolute lifesavers for protecting your valuable prints and documents! Measuring 17.25x13.375 inches, they're perfectly sized for 11x17 inch artwork with enough extra room for easy insertion and that handy self-sealing flap. The 2.8 mil thickness (double-sided) makes them durable and resistant to tearing, while still remaining crystal clear to showcase your work beautifully. What's really important is that they're acid-free and archival safe - meaning they won't damage or yellow your artwork over time like some cheaper plastic sleeves can. The side-seal construction makes loading your prints effortless, and the adhesive flap allows for secure closure that you can reopen and reseal as needed. They're waterproof and dust-proof, providing comprehensive protection whether you're storing, displaying, or shipping your work. The clarity is exceptional - colors and details show through perfectly without any distortion. With 50 bags in the pack, you've got plenty for current projects and future needs. Whether you're protecting limited edition prints, important documents, photographs, or art portfolios, these bags deliver professional-grade protection at an incredibly reasonable price. Your valuable work deserves this level of care - don't settle for anything less than archival quality protection!
