The writing instrument offered in the Lufthansa Worldshop is a Montblanc 145 (Platinum Line Classique). In direct comparison, a Pelikan 620, for example, is somewhat thicker; in overall size, both, however, are not far apart. Anyone seeking a fountain pen roughly in the size range of an M600 to M800 will find in the 145 a comparable, slightly slimmer counterpart.
