This movement tray measures 80mm x 57mm and made out of 2 layers of 3mm MDF. This tray holds two ranks of 3, 20mm square bases. The spacing allows for models that overhang their bases and is suitable for such games as Sharp Practice. The spaces for the bases are slightly larger than 20mm to allow for any extra paint or material which may be on your model's bases.
We use a high quality MDF which will not warp with normal use and can be painted, primed and finished the same way you have based your models.
