The Karajan was never made as a rollerball; an offered Karajan rollerball is therefore necessarily a counterfeit; likewise a Kafka rollerball. Collectors report increasingly well-made fakes, also in packaging design with a white star, which complicates recognition based on offer photos. Even pencils are not generally safe from fakes; collectors have already seen counterfeit Meisterstück mechanical pencils in the USA. Originality features such as the form of the star, the spelling of the word Meisterstück with ue, the number and form of the cap rings, the Pix embossing and the form of the clip end can be checked on careful inspection. Recommended is purchase from the specialist retailer.
