Starfinder RPG: Flip-Mat – Basic Terrain

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. Each Flip-Mat measures 24" x 30" unfolded, and 8" x 10" folded.
