To celebrate the upcoming 40th Anniversary of the first Battlemat being introduced into the market (May 21st, 1981), Chessex is bringing back some former mat colors plus a new color with a twist! These mats will be reversible with one color of vinyl on one side and a different color on the other. 34 1/2" X 48" playing surface. There are 53 columns of hexes per side. The width of the rows alternates between 32 and 31 hexes, so no play space is wasted..
