As requested by Wingspan fans, we've created neoprene player mats! Some players prefer neoprene because it's easier to pick up cards off of them. Each playmat is sold separately so you can buy exactly as many as you need (i.e., if you usually play Wingspan with 1 other person, you can buy 2). Removed from the cardboard tubes in which they're packed, they will fit into the Wingspan box.
These are the correctly sized neoprene playmats.
