When capped, a fake of the Montblanc Star Walker Resin fountain pen is barely distinguishable from the original. With the pen open, the clearest difference is at the nib. The original carries a 14-karat white-gold nib in a stand-alone, modern shape; the breather hole area is enclosed so that no slits are visible under the nib. The fake by contrast uses a bicolour-painted steel nib in white and gold, and slits are visible underneath. A typical marker on counterfeit nibs is the inscription "Iridium Point Germany" or "Iridium Point Paris". Another indicator is the use of piston converters which do not fit the original — Montblanc piston converters cannot be used in the original Star Walker. A weight comparison shows that the fake is heavier than the original. While the rollerball fake is hard to distinguish from the original, the fake fountain pen is easily identified by its typical counterfeit nib.
