Time for a new gaming mat release! This time it‘s something for fantasy or historical wargames – a cobblestone background. With no strict areas or streets, you can place your terrain scenery in gazillion ways to make each battle unique. These PVC mats come in standard 4x6, 4x4 and 3x3 sizes. But we can add squares, hexes, lines, or change the mat size according to your gaming table as easy as 1-2-3. Check them out at our website and let us know what you think!
