Natural Rubber Playmat for Wyrmspan

Why switch to natural rubber for Wyrmspan? Some players prefer this neoprene-like material because it's easier to remove cards from them.
Each playmat is sold separately so you can buy exactly as many as you need (i.e., if you usually play Wyrmspan with 1 other person, you could buy 2; Wyrmspan plays up to 5 players).
