Movement trays for rank and file-based units in strategy wargames like The Old World or Oathmark. These trays are based on standard 25mm square bases. With a low profile (3/32") lip, movement measuring can still easily be done from the side of the bases.

All trays come with a full complement of matched bases and are available both with and without pre-cut magnet slots that fit 1/8" drum magnets
