Battlefield In A Box Double-Sided 4'x6' City/Rural Gaming Mat BB956

It's a great combination of a steep landscape on one side and a gray urban layout for a destroyed city on the other. Perfect for the Eastern Front in WWII, which is what I wanted it for.But it comes folded in a box ("Battlefield in a Box") instead of rolled up in a tube. As shown in the picture, there are creases that aren't coming out despite careful ironing and laying out for about three weeks.

Good heavy duty mat, but as boxed rather then rolled it does have some creases
