The Extra Large Stamp & Die Storage Pockets are the same ones that you know and love but are now larger and sold in 50 packs! They are archival safe and are made of a clear/transparent 4 mil plastic. Securely store your clear stamps, wafer thin dies, stencils, embossing folders and more! The pockets are a great way to store your Avery Elle clear photopolymer stamp sets and custom steel dies. 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 measures 6 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.
