The gold filling of an engraving can fade with time but can be freshened up free of charge in every Montblanc boutique if the writing instrument was bought there. In terms of content, the personal signature is frequently preferred, because it appears more individual than an engraved name or mere initials; a full name is, however, more practical in case the writing instrument is lost and an honest finder is to be enabled to return it. Initials are regarded, regarding recognisability, as the least favourable variant. Anyone wishing possibly later to sell the writing instrument should consider that every engraving reduces the resale value. Alternative engraving sites other than the location on the cap intended by Montblanc are not offered ex factory.
