This smaller game mat is very handy! Use this smaller mat for the building you are entering instead of erasing all the terrain from your larger mat. Also great for gaming on smaller tables. This mat is one sided with one inch hexes for most styles of gaming. The back is felt lined to protect your table. The mat is slightly padded to make it easy to draw on and to protect your miniatures as well as your gaming surface. Recommended markers are the Staedtler non permanent markers. Sold on this site in sets of 4 or individually in case you have killed just your black.
