The [[Stylomine]] brand was officially registered in [[1921]] with n. 199226, and was used by ''Yves E. Zuber'' for his pencils. The fountain pen production began only in [[1925]] with some [[safety]] models in black or red marbled black hard rubber. It was relevant also for the production of [[overlay]]s in both rolled gold or precious metals. But in this period the product most characterizing the company's production is the mechanical pencil ''Autostyl'', in which the mine is automatically replaced after exhaustion. The production of mechanical pencils will continue for all following years, with different names such as ''Stylomine Automatic'' and ''Stylomine 202''.

But the fountain pen which made famous [[Stylomine]] is the [[Stylomine 303|303]] model, introduced in [[1930]] and equipped with a series of very peculiar technical solutions, as a large-capacity and very functional [[bulb filler]] system, very functional and high-capacity thanks to a breather tube ingeniously connected to the feeder (patent {{Cite patent|FR|712327}}), which allowed the full loading of the pen with only four or five strokes.  

But the fountain pen which made famous [[Stylomine]] is the [[Stylomine 303|303]] model, introduced in [[1930]] and equipped with a series of very peculiar technical solutions, as an advanced [[bulb filler]] system, very functional and with high-capacity thanks to a breather tube ingeniously connected to the feeder (patent {{Cite patent|FR|712327}}), which allowed the full loading of the pen with only four or five strokes.  

In [[1933]] was created a very special re-entrant nib mounted on a spring that was made by screwing the cap back by the pressure of an inner tip (see {{Cite patent|FR|737930}}). This system, along with the re-entrant nib, was used in the new model [[Stylomine 303B|303B]], produced in three versions corresponding to three different sizes. The loading was a refinement of the previous system of [[Stylomine 303|303]] and was also used for the model [[Stylomine 303C|303C]], without re-entrant nib, which in addition to the three previous versions was made in [[celluloid]] and with a fourth size, large enough to call it [[Mastodonte]].  

A questo modello venne aggiunto nel [[1933]] un particolarissimo gruppo pennino montato su una molla che veniva fatto rientrare con l'avvitamento del cappuccio grazie alla pressione di una punta interna (vedi brevetto {{Cite patent|FR|737930}}). Questo sistema, insieme al pennino rientrante, venne usato nel nuovo modello [[Stylomine 303B|303B]], prodotto in tre versioni corrispondenti a tre diverse misure. Il caricamento era un perfezionamento del precedente sistema della [[Stylomine 303|303]] e venne usato anche per il modello [[Stylomine 303C|303C]], senza pennino rientrante, che oltre alle tre versioni precedenti venne realizzato in [[celluloide]], e con una quarta dimensione, sufficientemente grande da farla denominare [[Mastodonte]].  

But the most significant invention of the company, which is a bit its distinguishing feature,  is the revolutionary [[accordion filler]] a peculiar variant of breather tube filler which allowed a large ink capacity, in which the pumping was carried out thanks to an ink sac with accordion walls, and in which the bulb was replaced by a button under the bottom, consisting of a glass ampule inserted to slide in the rear end of the body, that you could press to make the pumping, use and also to see the remaining ink.

Particular interest come also from the development of the [[Stylomine 303D|303D]], an [[hooded nib]] model, perhaps the first ever produced. Its patent ({{Cite patent|FR|850525}}) is in fact from [[1938]] and anticipates by several months the corresponding ({{Cite patent|US|2223541}}) [[Parker]] patent for the [[Parker 51|51]], but the company still had patented an hooded nib since 1932 ({{Cite patent|FR|750689}}). So the company seems to have beaten [[Parker]] in terms of innovation. In this case, however, we don't known the exact dates for the market appearance of the model, which in some cases is reported as much later.<ref>As reported in [http://web.archive.org/web/20081111115149/ http://www.stylos-francais.fr/stylomine3.php this article] the introduction would be in 1947.</ref>  

E' di particolare interesse poi lo sviluppo del modello [[Stylomine 303D|303D]], dotato di pennino carenato, forse il primo mai prodotto, il relativo brevetto ({{Cite patent|FR|850525}}) infatti è del [[1938]] ed anticipa di vari mesi il corrispondente brevetto ({{Cite patent|US|2223541}}) della [[Parker]] per la [[Parker 51|51]], ma l'azienda aveva comunque brevettato penne a pennino coperto fin dal 1932 ({{Cite patent|FR|750689}}). Si può pertanto ritenere che l'azienda francese abbia battuto sul tempo la stessa [[Parker]] in termini di innovazione. In questo caso comunque non sono note date esatte per la comparsa del modello sul mercato, che in alcuni casi viene riportata come molto più tarda.<ref>secondo quanto riportato in [http://web.archive.org/web/20081111115149/http://www.stylos-francais.fr/stylomine3.php questo articolo] l'introduzione sarebbe del 1947.</ref>  

Around [[1937]]<ref>this is what is reported in [http://web.archive.org/web/20081111115149/http://www.stylos-francais.fr/stylomine3.php this article].</ref> was launched also the model [[Stylomine 303V|303V]] (the date is still somewhat uncertain), with the [[accordion filler]], a new streamlined shape style and the use of a plastic material body (which makes one suspect a later appearance).  

Nel [[1937]] circa<ref>questo è quanto riportato in [http://web.archive.org/web/20081111115149/http://www.stylos-francais.fr/stylomine3.php questo articolo] ma l'uso di materie plastiche lascia la cosa incerta.</ref> venne lanciato il modello [[Stylomine 303V|303V]] (la data comunque è alquanto incerta), che adottava il nuovo [[caricamento a fisarmonica]], con un nuovo stile più svasato rispetto a i precedenti e l'uso di un corpo in materiale plastico (cosa che fa sospettare una apparizione più tarda).  

The postwar period saw the spread of the hooded nib [[Stylomine 303D|303D]] model, flanked by other models such as the [[Super 303]] with round tip nib. The [[accordion filler]] was maintained replacing the glass button with plastic material. In 1947 were introduced the  ''Stylomine 404'' mechanical pencil and in 1948 was introduced the ''Stylomine 707'' ballpoint pen.
