This set includes three packages of clear storage pockets in small, large, and extra large sizes, with a total of 150 pockets. The small pockets measure 5-1/8" x 5", the large pockets 5-1/2" x 7-3/8", and the extra large pockets 6-3/4" x 9-3/8". Made from 4 mil transparent plastic, these archival-safe pockets are ideal for storing clear stamps, wafer-thin dies, stencils, embossing folders, and more. Each pocket features a tuck-in flap to keep contents secure. For added stability, stamps can be removed from retail packaging and taped to a sheet of cardstock before sliding into the pocket. The pockets can be stored in a CD/DVD basket or clipped up for easy access. Each package contains 50 pockets, making this a versatile solution for organizing craft supplies efficiently.
