Leuchtturm Grande Banknote Pouch, reference 308439, pack of 5 units, is a white banknote filing sheet, each measuring 98x216mm. Leuchtturm is a German brand founded in Hamburg in 1917, considered a world leader in collection systems for philately and numismatics, with a catalog of over 6000 items covering more than 140 collection areas. It is made of transparent, acid- and plasticizer-free film, which protects banknotes from moisture, dust, and direct contact with fingers, while keeping the surface visible for consultation. The white tone distinguishes this reference from the black version of the same Grande line, giving the filing system a lighter and more neutral appearance.
