Our magnets can be used on any magnetic receptive surface.  Some customers do not need a board because they intend to use their magnets on their refrigerator, a magnetic wall or on a magnetic white board from an office supply store.  White boards are great if you are looking for a larger surface.  Our 18” board offers two sides, a progress chart, the ability to fold it and the ability to hang it anywhere you want.  So the choice is yours.
