Square Chalk Box w/ Magnet

Black Rubber Square replacement

Removable Magnet

Master chalk single piece

Please note : One issue that may come up is the magnetic polarity…you may find that our replacement actually ‘repels’ or pushes away from your magnetic piece. If this happens, all you need to do is remove the cube of chalk from the holder, flip the magnet over, and reinsert the chalk into the holder. That will correct it.
