CHX 97246 Megamat

This mat features specially-made vinyl in an eye-pleasing oyster color designed to give a flat surface for writing. Using water-soluble overhead-projection pens you can write on the vinyl and remove later with water when the drawing is no longer needed. This approximately 34½" x 48" mat is double-sided with 1" squares on one side and 1" hexagons on the other.
