The Pocket Page and Tag Bigz Pro Die by Sizzix can be used to make mini albums, cards or embellishments for a layout. This die can cut hundreds of materials, including paper, cardstock, chipboard, craft foam, leather and more. The pocket measures 4" x 6 1/8" when assembled and the tag insert measures 3" x 5 7/8". This die is designed only for use with the Big Shot Pro Machine. It requires a Big Shot Pro Cutting Pad and Crease Pad (all items sold separately.) When using striped material, orient your paper so it lines up with the cut blades and not the edge of the die for best results.
