The "12 Man Movement Tray" has been designed to be suitable for rules such as Sharp Practice. 

Made from 2mm MDF, the tray comes in two pieces (which need to be glued together with woodwork quality PVA) and has the 8 circular bases included.

The diameter of the hole is 26.3mm. This allows a comfortable fit of a UK 2p coin

The diameter of the circular base is 25.9mm and once painted, will be a good fit into the holes in the tray.

This tray is compatible with the "8 Man Movement Tray" and 4 versions of  "6 Man Skirmish Trays" also available on this webstore.
