Extra Large Stamp & Die Storage Pockets are archival safe and made of a clear/transparent 4 mil plastic. Securely store your clear stamps, wafer thin dies, stencils, embossing folders and more! Each pocket will fit one standard 6x8" clear stamp set. Store the pockets in a storage basket/bin or clip them up if you wish. Each pocket measures6 3/4" x 9 3/8" and includes a flap that tucks in to keep your stamps and dies secure in the pocket. For greater stability, consider taking the stamp set out of the retail packaging and tape it to a sheet of card stock. Slide the stamp set/card stock sheet into the pocket.
