Sellers working with foreign or stolen product images count as not reputable and should be avoided. 'pen-seller' is mostly rated reputable in the forum, with positive ratings and, by his own statement, direct sourcing from Hamburg; several collectors have bought there without problems. Low prices alone need not be an indication of counterfeits, since dealers have different purchasing conditions. To safeguard, a detailed image comparison with the fake overviews on Fountainpen.de and a phone seller contact before purchase are recommended.
