Indications of originality are, among others, a clip ring whose 'Germany' embossing was, in the early period, stamped and not laser-engraved, as well as a clean and correctly engraved nib. Counterfeits often reveal themselves through faulty inscriptions like 'IRIDIUM POINT PARIS', which do not occur on a real Montblanc. The StarWalker officially exists only in two colour variants, Resin Black and RubberLine; deviating versions are not authentic. In case of doubt, assessment at the authorised specialist retailer or comparison with documented examples is recommended.
