Decorative stones that are not stones at all. They consist of either steel or cast iron and combine the decorative with a sustainable way of recycling residual products from the iron foundry. They have a diameter of approx. 5 to approx. 25 mm and are vacuum-packed with 15 pieces in each. It may not sound like much, but it is a rather eye-catching size. Mars Rocks have a rustic look and can be used for many decorative purposes, as they are all worn in individual shapes. The starting point of their geometry is a star, rectangle or circle.
