The Magic Whiteboard is a Whiteboard on a Roll, and it is perfect for home, school and the office, from the playroom to the classroom to the boardroom. It is completely erasable and sticks to any hard, flat surface using electrostatic technology, so no adhesive is needed. You can reuse each sheet more than 20 times and recycle it when you’re ready to throw it away. Any ink from dry erase markers will rub off easily even if left on for days, but note that dry erase ink can rub off when sheets are folded or rolled.
