LITKO Game Accessories announce the availability of their new Door Markers:
From their announcement:
Door markers are the perfect addition to any dungeon crawl game. Add them to your RPG maps for added realism, or to upgrade any cardboard components for board games. The large doors represent two halves, this way you can show partially open, or closed doors. Medium sized doors, trap doors, and portcullis markers also available in the Jim’s Lab section of the litko.net website.
