Create a Tri-Shutter card with ease with this Bigz Pro die by Sizzix. When assembled, this die-cut shape measures 11.25" x 5.5" when open and 3.75" x 5.5" when closed. The die itself measures 12" x 12 3/4" and is compatible with the Big Shot Pro Machine (sold separately) and requires the use of a Big Shot Pro Cutting Pad, a Big Shot Pro Crease Pad and a 12" x 12" piece of paper. For best results, when using striped paper, line it up with the cut blades. Bigz Pro dies will cut a wide variety of materials, including leather, metallic foil and sandpaper (in limited use).
