Counterfeits concentrate for economic reasons primarily on the market leader with high numbers and high shop price, in the writing-instrument area on Montblanc. Other brands like Pelikan, Caran d'Ache, Graf von Faber-Castell or OMAS hardly play a role in counterfeits; occasionally, however, fakes of Cartier or Louis Vuitton (LV) are also known. The phenomenon thus corresponds to that of other sectors, e.g. watches (Rolex, Breitling) or lighters (Dupont).
