OptiMA® offers custom printed dry erase magnetic sheets that adhere to any smooth steel surface or magnetic whiteboard. Available in sizes up to 45" x 96", these magnets feature a top-notch dry erase surface and strong magnetic adhesion. You can customize the design, whether it's a black and white grid, a colorful scheduling board, or anything else. The printed image is protected by a durable dry erase surface that won’t crack or peel. When not in use, roll the magnets with the print facing out and store them in a heavy-duty corrugated tube.
