This cutting mat is custom designed for creating the most intricate paper crafts with the "Cricut Machine". The printed rulers and markings facilitate convenient and accurate use. The surface treatment gently adheres to paper to ensure smooth and accurate cuts every time. This package contains two sheets. It works best for paper up to 6" x 12". Using both mats allows you to cut one thing while working on another. Mats last 25-40 full mat cuts depending on paper used.
