The Robbing Peter to Pay Paul Bigz Pro Die by Sizzix cuts cardstock, chipboard, fabric, foam, leather, metallic foil, paper and more. It is designed for use with the Big Shot Pro only and is not compatible with other machines. A Big Shot Pro Cutting Pad and Crease Pad are also required for use - each sold separately. The Robbing Peter to Pay Paul Bigz Pro Die measures 12" x 12 3/4" and the die-cut shape measures approximately 9" assembled. This die shape also features darts and dog-eared corners for easy alignment. Please note that this die design may be angled, so if you are cutting striped patterned paper or striped fabric be sure to line up the material with the cut blades and not the edge of the die. This will ensure a great result!
