A reliable recognition feature is the nib, which counterfeiters have so far not been able to imitate with high quality. Since Montblanc does not sell any replacement nibs to end customers and repairs only run via the authorised service, it is additionally uneconomical for counterfeiters to fit individual original nibs into imitations. A purchase from a commercial provider with a 14-day right of return additionally allows checking with the specialist retailer. A personal pickup additionally enables visual inspection of further details before purchase.
