With the Pathfinder Flip-Mat: Basic Environments Multi-Pack, you can focus on what matters the most: the action in your game. A special coating on each Flip-Mat allows you to use wet erase, dry erase, AND permanent markers with ease! Removing permanent ink is easy-simply trace over any permanent mark with a dry erase marker, wait 10 seconds, then wipe off both marks with a dry cloth or paper towel. This set includes two flip mats, each measuring 24" 30" unfolded, and 8" x 10" folded.
