Several counterfeits of the Montblanc StarWalker edition exist in differing quality. A red rollerball plagiarism is a relatively well-made counterfeit with an engraved serial number on the cap and a grip section that comes close to the original. The clearest distinguishing feature is the colour of the barrel. Original StarWalker rollerballs are currently offered in only two variants: as Resin in black precious resin and as Rubber Line with a rubberised surface and laser engraving. Counterfeits of both exist. Beyond that, additional colour variants are known among the fakes: red, blue, green, black, white and a rubberised gold version.
