Peel & Stick Pocket - Letter Size - Clear Archival Plastic. Putting up permanent signage or attaching documentation to a machine or wall doesn't have to be difficult. StoreSMART's Peel & Stick Polypropylene Letter Size Pockets do the job beautifully! They're made of lightweight, crystal clear archival material, so your documents will be safe. The backs are coated with clear, permanent adhesive, allowing you to attach them pretty much anywhere you want—all without the fuss of lamination, the mess of tape and glue, or the frustration of waiting for a custom sign order to arrive. Just use 8 ½” x 11” sheets to convey your message, and swap papers out whenever you like. Nothing could be easier!
