from the back cover: Storm the castle! Whether your players want to defend or storm a castle, Pathfinder Flip-Mat: Castles Multi-Pack has you covered. This set's four sides each feature a different castle, keep, or other fortification. From a lonely mountainside keep to a shining castle on an isle, a dingy fort on the edge of the wilderness, or even a bastion within the city, you'll find a suitable site within. This set includes two flip mats, each measuring 24" x 30" unfolded and 8" x 10" folded. Their erasable coated surfaces 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, and with these castles at hand, you'll be ready for an siege or invasion!
