I designed these bases for late c.17th infantry battalia for use with For King and Parliament. These bases take minis drawn up two ranks deep; useful late in the c.17th, when units formed up in shallower formations.

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 three bases, making a unit 25cm wide (the same unit size that  Simon uses on a 30cm grid): these FK&P3 bases are approximately 85mm wide and 50mm deep.
