Sizzix Sidekick Accessory Cutting Pads Gray are specially designed for use with the Sizzix Sidekick Machine. Made from durable, high-quality polycarbonate plastic, these transparent cutting pads are used with Sizzix chemically etched wafer-thin dies, including Thinlits and Framelits dies. Simply place the die and material between the cutting pads and roll them through the machine for precise die-cutting. Each cutting pad measures approximately 2.5 x 4.875 inches and is designed for use on both sides, providing thousands of cuts before replacement is needed. As with all cutting pads, bowing, scratches, and cut marks are normal signs of use and do not affect performance. Cutting pads are consumable items and will need to be replaced periodically. These items are not covered under the Sizzix warranty.
