The 12-inch by 12-inch Adhesive Pad-29-0386 (for the Expression machine 29-0300 only) is a self sticking pad that keeps the material being cut flat so that there is no tearing on the paper or vinyl. Since the pad retains its stickiness for a limited amount of cuts we recommend buying extra pads. The pads are also great for storing the paper or vinyl that has already been cut. Two mats included. Custom designed for creating the most intricate paper crafts with the Cricut machine. Printed rulers and markings facilitate convenient and accurate use. Gently adheres to paper to ensure smooth and accurate cuts every time.
