Within the first 14 days of new purchase, the nib width is exchanged free of charge by Montblanc, provided the nib is not bent. Later exchanges run via the boutique or factory service against the usual repair flat fee, whose exact amount Montblanc only states after assessment. Some boutiques exchange the nib directly on site, which significantly speeds up the process. A precondition is generally that a matching desired nib is in stock.
