The Big Book of Battle Mats is a collection of 58 battle mat pages in a lay flat spiral bound volume, A4 in size per page. Designed to be carried with your RPG books and to provide easy access to a variety of environments to be used for encounters. The spiral binding allows the book to be laid flat and for each two page spread to be used as a single mat. All designs have a 1" grid either as an overlay or as part of the design. Pages are laminated so can be drawn upon and wiped clean using wet or dry wipe markers or chalk pens. Designs are arranged so that they can be used as single pages or as part of a double page spread.
