Set of three cards in convincing design and craftsmanship quality. Inspired by the world-famous Tangram game and in bright Pantone colors magenta, yellow and lime. The cards are printed on a very special paper, MetaPaper Eco Fibre Cream 320 g/m² on an original Heidelberg cylinder from 1954 in Erik Spiekermann's studio. The FSC-certified unbleached paper made from 30% straw fibers and 70% fresh fiber pulp is much more stable than grass fibers, for example, and much stiffer than wood fibers due to the addition of straw. This gives the material great strength. Straw is a renewable raw material that adds a sustainable type of fiber to the raw material base. The stalk that remains after the grain has been harvested is used, so straw improves the ecological balance.
