The deepest caves and hidden passages of the notorious subterranean Darklands hold as many great treasures as they do formidable dangers, such as monster lairs, fungus-filled tunnels, treacherous underground rivers, and molten hot magma! This set includes two flip mats, each measuring 24" x 30" unfolded, and 8" x 10" folded. A Flip-Mat's coated surface can handle any dry erase, wet erase, or even permanent marker. Usable by experienced GMs and novices alike, Pathfinder Flip-Mats fit perfectly into any Game Master's arsenal!
