Collectors report that typical recognition features are the three cap rings (especially the middle one, which on originals should not appear bulgy), the inscription "Montblanc * Meisterstück * Pix *" including inner imprint "Pix" on the clip, as well as the round, not angular, bend of the clip; the points of the star should not be too sharp, and the gold closure ring at the cap base must have the right width. On the website fountainpen.de, detailed comparison PDFs ("Vergleich-Rollerball.pdf") as well as a newsletter article with recognition features can be found. With a clear counterfeit, the following procedure is recommended: notify the seller, inform eBay, notify Montblanc and, in extreme cases, engage a lawyer or file a complaint.
