The "24 Man Movement Tray"  has been designed to fit with other trays in the 25mm round range.  

Made from 2mm MDF, the tray comes in two pieces (which need to be glued together with woodwork quality PVA) and has the 24 circular bases included. The circular bases are 25mm diameter and the holes in the top layer are 0.4mm bigger allowing a good, but not too tight fit once the tray and base are painted.

This tray is compatible with the range of 25mm rectangular infantry trays and "twin trays" for skirmish units.
