Whether you're sailing into a stormy naval battle or sneaking into a ship to steal buccaneer plunder, Pathfinder Flip-Mat: Bigger Ship has you covered. Each side of the Flip-Mat features the deck plans for a truly massive vessel. One side covers the top deck of the behemoth galleon, while the other details the lower decks. Measuring 27" x 39", this Flip-Mat features a coated surface that's designed to handle any dry erase, wet erase, or even permanent marker.
