This is a 1 inch grid tile press designed for making miniature terrain look more interesting. Terrain with squares that are offset to each other create depth, and drastically improve the look of your terrain when painted. The attached photo is of some 1" thick insulation foam from Home Depot.
There are 2x2, 4x4, and 6x6 tile files available.
