The "5 Man Skirmish Movement Tray for 20mm bases" comes as a 2mm MDF base with a 3mm MDF lattice top.  The gaps between are 1/2"  

The tray will need assembly with a woodwork grade PVA and is supplied unpainted. 

Each square slot has been drawn to accept models that are based on 20mm squares. 

Mid point of both front and rear has "V" marks to indicate the centre of the unit.
