Collectors unanimously confirm that Montblanc writing instruments are unrestrictedly suitable for everyday use, from filigree Solitaire models to the classic 146/149 line. Reports include daily use of a 146 over more than ten years without loss of function or substance, as well as the use of a Bohème or Jules Verne as a constant companion in a professional environment; even manual activities the pens endure. Anyone who wants to write with quality should use the pen consciously and not lock it away from exaggerated worry, since regular use keeps the pen in shape. High-priced materials such as carbon or gold change nothing about robustness but are to be handled more care-consciously. With frequent use collectors recommend a rollerball or mechanical-pencil model as a complement to the fountain pen, in order to avoid changing ink in meetings.
