I designed these bases for infantry battalia in For King and Parliament. They are cut from 2mm MDF; 3mm diameter magnets (sold separately) can be fitted into the holes to secure them in storage or transport. The edges of the bases can be chamfered with a craft knife and the naturalistic appearance of the wobbly edges helps them to merge into the playing surface. 

This pack includes six bases, making a unit 19cm wide for use with a 20cm grid. The FK&P6a and FK&P6b bases are approximately 63mm wide and approximately 47mm and 23mm deep, respectively. A pair have the same footprint as the FK&P6. They can be used in their own right, or to add extra ranks to the FK&P6.
