This pair of Cutting Pads works in the SophistiCut, Big Shot, BIGkick and Vagabond machines. Constructed of high-quality polycarbonate plastic, these see-through Cutting Pads allow for easy die-cutting and embossing of Sizzix chemically etched dies (Clearlits, small Embosslits, small and medium Sizzlits) and embossing products (Simple Impressions) in the machine. Simply sandwich the die and material to be cut between the Cutting Pads and roll through the machine. Add a Sizzix Adapter (sold separately) to create a sandwich for accommodating competitors' wafer-thin dies. Each Cutting Pad measures 4.875 X 2.5 X .125 inches and lasts for thousands of cuts. All Sizzix Cutting Pads are meant to be used on both sides. When both sides of the Cutting Pads are worn out, it is time for replacement Cutting Pads.
