Designed by Jen Long-Philipsen, this Bigz Pro die can be used to cut most materials, including leather, paper, cardstock, fabric, magnet, foam, metallic foil, chipboard and more. Please note that because this die measures 12" x 12 3/4", it can only be used in the Big Shot Pro Machine. You will also need a Big Shot Pro Cutting Pad, a Big Shot Pro Crease Pad and 12" x 12" material (all items sold separately). This envelope will coordinate with the Long Decorative Card Bigz Pro Die (sz-658489), which is sold separately. When assembled, your envelope will measure 9 1/2" x 4 1/8".
