I have a single Geek Villain mat, with a 15cm cross grid. Unfortunately the grid is slightly off centre, so the mat is only 11 boxes wide, with two half boxes on either side, instead of  the usual 12. It is the usual 8 boxes deep.

The plains design - largely grass with patches of stone - is perfect for many parts of Europe, Asia and North America. 

NB one image shows the mat without a grid, which gives a good impression of the colour of the mats.
