Perfect for materials such as special cardboard, chipboard, passe-partout and backed materials, the StrongGrip cutting mat has been carefully designed for heavy materials. As an interface between your material and your Cricut machine, each reusable mat serves to keep your material in place when cutting. After cutting, the finished cut can be easily removed. Each mat offers the best possible adhesion and a long service life. For use with Cricut Maker and Cricut Explore cutting machines. TIPS When storing, the clear film cover should remain on the mat to keep the mat free of paper residue and dust. Use the scraper to scrape off excess parts and the spatula to gently remove cut images. To ensure optimal performance, the recommended material types should be used on the mats.
