First versions were made ​​of hard rubber, and there are also [[overlay]] versions in gold rolled metal. The initial production was certainly very small, since have been found handwritten guarantee scraps dated [[1933]], signed individually by the  ''Dante Zerollo''. This first production was followed by new celluloid versions, made ​​in beautiful marbled colors or wood grain, and with extremely refined working as a peculiar spiral faceting.

Given quality and sophistication of the processes, and the presence of similar celluloid, it has been suggested that the production of these pens have been entrusted to the [[OMAS]], but there is no proof, or reference document in this regard that let support this hypothesis, and the similarity or the quality of the work can not be considered a final element, as it can be assumed that [[Zerollo]] could have purchased some parts from [[OMAS]].<ref>in [http://www.fountainpennetwork.com/forum/index.php?showtopic=4467&st=0 & # entry116468 this article] is cited research by Luca De Ponti on nibs and clips.</ref>

The company had some success, and was able to sell its products abroad relying on [http://en.wikipedia.org/wiki/Alfred_Dunhill Dunhill] for the English market and on [[Unic]] for the French one. But although functional it was still a pen equipped with a very complex and delicate mechanical system, difficult to repair, which made it brittle and all in all not much more convenient to use than the simple and straightforward solution to carry around two pens. While maintaining production based only on this particular model, and not being able to produce further innovation, with the fall of the interest aroused in the initial period, [[Zerollo]] suffered a progressive decline disappearing from the market after the Second World War.
