There is no Montblanc Scott Fitzgerald rollerball in the Writers Edition; the edition comprises exclusively fountain pens, ballpoints and pencils. If a Scott Fitzgerald rollerball is offered, it is therefore necessarily a counterfeit. The packaging is barely distinguishable on the plagiarism from the original; at most the fake one looks somewhat darker. On the writing instrument itself two main features are decisive: the Scott Fitzgerald exists only in white, every black, blue, green or red variant is a fake; however, white counterfeits also exist. The shape also differs: the counterfeit is clearly slimmer, the original looks more pot-bellied. On closer inspection the grip section of the counterfeit comes from a Bohème counterfeit; on it the imprint 'Bohème' is even recognisable. Montblanc does not reuse parts from other editions in the Writers Editions, which is also regarded as a typical counterfeit feature. The included rollerball refill is also counterfeit and barely distinguishable from the original. In the case described, the pen was acquired for 150 euros in a Milanese designer shop and broke after only a short time.
