A card index box simplifies learning. It doesn't matter whether it's simple vocabulary or learning complex facts in the context of studies or professional training. The principle of "question first, answer later" works for learning in all phases of life. Card index boxes are available in many different sizes, most common are DIN formats in landscape format. Depending on the size, the boxes differ in their capacity. HAN wooden filing boxes are made of high-quality, FSC-certified natural wood (birch). They are equipped with a metal base plate in which the matching metal support dividers can be anchored. The material "wood" makes the card index boxes visually valuable objects that can also be integrated well into the private living environment. There, for example, they are ideal as a photo box for the family's photo collection.
