The problems of this mechanism were mostly related to providing adequate positioning to the ''[[pressure bar]]'' (it was usually glued). The system was not particularly sturdy, nor elegant, and it assumed however the possession of a match, without which it turned out useless. To this problem some producers had obviated making the [[clasp]] dismountable and usable to the place of the match, or creating an opportune protuberance on the head of the cap or using some alternative form in order to furnish an adequate partridge.

Il sistema pertanto risulta alquanto primitivo dato che nessuno aveva trovato una soluzione al suo problema più rilevante, quello per cui in caso di rottura del sacchetto di gomma interno, l'inchiostro poteva fuoriuscire dal forellino presente sul corpo della penna con le immaginabili poco gradevoli conseguenze.<noinclude>

The system is therefore quite primitive since no one had found a solution to its most important problem, that in case of breakage of the inner rubber bag, the ink could escape from the hole on the body of the pen with the imaginable unpleasant consequences.<noinclude>
