This pair of cutting pads has been specifically designed for use with the Big Shot Plus machine. Made from high-quality polycarbonate plastic, these transparent cutting pads allow for easy die-cutting of Sizzix steel dies (Bigz Plus) in the Big Shot Plus machine. Simply place the die and the material to be cut between the cutting pads and roll them through the machine. A premium crease pad may be required instead of a cutting pad when die-cutting Sizzix steel dies with a score line. Please note that all cutting pads are consumables and need to be replaced from time to time. The items are not covered by the Sizzix warranty. They tend to warp and leave marks, but this is completely normal during use.
