Do you have it portable or pull down
Magnetic means that you can use magnetic accessories or simply that a magnet will stick to the writing surface. They are magnetic receptive. As for a "portable" unit - we do have a Roll Up Magnet that will stick to your whiteboard or chalkboard if they are magnetic receptive. You can check that by simply trying to stick a magnet to your board. If it does, then these will work.
