This pair of Cutting Pads was specially designed for use in the Big Shot Plus Machine. Constructed of high-quality polycarbonate plastic, these see-through Cutting Pads allow for easy die-cutting of Sizzix steel-rule dies (Bigz Plus) in the Big Shot Plus machine. Simply sandwich the die and material to be cut between the Cutting Pads and roll through the machine. A Premium Crease Pad may be needed in place of one Cutting Pad when die-cutting Sizzix steel-rule dies containing crease rule. Please note, all Cutting Pads are consumable items and will need replacing from time to time. The items are not covered by the Sizzix Warranty Cover. They are prone to bowing and marking but this is completely normal through use.
