Recommended are especially Lesny (schreibgeraeteaufderbruecke.de) because of its broad range and procurement possibilities, as well as the Swiss shop Landoldt Arbentz on Zurich's Bahnhofstrasse, which also delivers to Germany. For demanding handmade accessories of Arizona full-grain leather, the family business Ludwig Kopp in Offenbach (trademark LK) comes into question, which delivers via selected specialist retailers; a dealer directory is available on request. The latter pieces lie, however, in the upper price segment.
