17 cards in DIN A7 format (7.4 x 10.5 cm) were printed using the offset process. Finn cardboard is made of high-quality natural paper and is approximately 0.2 mm thick. PLEASE NOTE: We have created new packaging for the set. It is now packed in a sturdy kraft paper box (brown) with beautiful gold foil printing. We also added a new card to the set, bringing the total to 17 cards. As with recycled paper, the cardboard can show small irregularities due to the paper fibers. The back of the paper is also in minimally different shades of white, because the natural paper is completely unbleached.
