The seller is described in the collector scene as reputable, with proper invoice and the usual 2-year warranty. When buying from a commercial dealer in distance selling (internet, telephone, doorstep), additionally a 14-day return right exists, also without reason. Important: Montblanc principally forbids its authorised specialist dealers distribution via the internet — reputable eBay sellers are generally not authorised dealers; the warranty thus comes from the seller themselves, not directly from Montblanc. Warranty cards are handed over depending on supplier with or without factory stamp.
