Cohas Chalkboard System Magnetic Backed Lined Chalkboards are made from material that looks like classic chalkboards, but will attract to any magnetic surface. These chalkboards have lines, for even and straight writing, and are just the right size for use on refrigerators, metal doors, cabinets, whiteboards, and more. They come embedded with real chalk art, a simple chalk line border, and faint writing guidelines, giving you a large area for lettering or illustration. This kit comes with three bright colored wet-wipe liquid chalk markers. The premium markers feature reversible tips, perfect for making thick and thin chalk-like lines. The markers ink will remove easily with water. When you are ready to change your message or artwork, just use a damp cloth or sponge. This product is not recommended for children to use. Boards are easy to clean and reuse when used with the included markers. Do not use regular chalk, Expo and dry erase markers, and metallic markers on the surface. Certain brands may cause staining; test other brand markers before use on board. Board is guaranteed to stick to any surface that magnets are attracted to.
