Thanks to the hardfoam series "Rock", high mountain ranges can be created authentically. The rock wall and the rock portals are matching in surface structure and colour so that they can be combined with each other. The handling of the hardfoam products is easy. The products can be cut with a hobby knife or a slitting saw and smoothed with a fine rasp. You can even form the products by heating them with a hair dryer. The hardfoam rocks can be fixed on the layout with a hot-melt adhesive or a rock compound.
