Measuring 5 1/2"" x 6"", a Bigz die is the largest Sizzix die. It die-cuts thick materials, including cardstock, fiber, fabric, foam, magnet, leather, metallic foil, paper and sandpaper (in limited use). Its wider size offers you more design options. Please note that this die is designed for use only with the BIGkick and Big Shot Machines and requires the use of a pair of Cutting Pads.
