From Paizo's website:
RPG players like their characters to be the center of attention, and there’s no better place to put them on center stage than the theater! Flip-Mat: Theater features an immense theater scene perfect for a titanic battle or high society encounter, complete with a large stage, private boxes and balconies, and lots of space for the audience to get into trouble.
GameMastery Flip-Mats are designed to make your game portable and affordable. They're made with durable, laminated card stock and can handle dry erase, wet erase, and even permanent marker!
Flip-Mats are constructed of durable laminated card stock (~70 lb paper—comparable to that of a restaurant menu). They measure 24" by 30", and quickly and conveniently fold down to 8" by 10" (slightly smaller than a sheet of notebook paper). The 1" grid extends fully to the edge of the maps for a full 720 square inches of usable area.
