This adhesive-backed Chalkboard vinyl from Silhouette America is designed to be cut with the Silhouette Cameo Electronic Cutting Tool (sold separately). It's easy to cut, apply and remove from glass surfaces and has a stronger adhesive for indoor and outdoor use. It's gentle enough for most indoor walls, but resilient enough to withstand the sun and weather. This chalkboard vinyl can be used for a variety of projects and once your project is complete you can write and erase on it like a real chalkboard. Cut detailed designs and professional-quality titles up to 12" tall and 4' long with your Silhouette. Use together with the Silhouette premium transfer paper (sold separately) for easy application. Includes one 12" x 4' roll.
