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 1954 Heidelberg cylinder in the studio of Erik Spiekermann. The FSC-certified unbleached paper made from 30% straw fiber and 70% virgin fiber pulp is much more stable than, for example, a grass fiber due to the addition of the material straw and much stiffer compared to wood fiber. This gives the material great strength. Straw is a renewable resource that adds a sustainable fiber type to the raw material base. The stalk that remains after the grain has been harvested is used, which improves the ecological balance.
