This pack of 5 magnetic dry-erase sheets features a smooth writing surface and a magnetic back. Write on them with a dry-erase marker, wipe them off and use them repeatedly; an excellent alternative to sticky notes. Use each magnetic whiteboard for fridge use at home, office, or school. Write down chores, to-do lists, and any messages and notes and stick them on the refrigerators, metal cabinets, and other metal surfaces. They also make excellent teaching tools thanks to their reusable nature. Each magnetic whiteboard measures 9 x 12 inches.
