The novelty is not so much the way in which the ink is aspirated as the fact that in this case it is no longer necessary to fill the pen by dipping the nib inside the bottle. During the opening phase, in fact, it is possible to extend through the feeder a small metal tube (the ''snorkel'') with an aeration duct that allows the passage of the ink through it instead of through the nib.

Si tratta senza dubbio di uno dei più complessi (e per certi versi affascinanti) sistemi di caricamento mai utilizzati, che permette di non sporcare il pennino e che per questo veniva ampiamente pubblicizzato. Il principale svantaggio resta quello della capienza, in genere infatti l'unità di caricamento che contiene il sacchetto è abbastanza piccola e la penna contiene poco inchiostro.<noinclude>

It is undoubtedly one of the most complex (and in some ways fascinating) filling systems ever used, which allows you not to dirty the nib and for this reason it was widely publicized. The main disadvantage is the capacity, generally in fact the loading unit that contains the sac is quite small and the pen contains little ink.<noinclude>
