The celluloid introduction corresponded to the launch of a new line of pens, called Infrangibile whose production was maintained until the 40s. Albeit with different restyling and technical changes, as the switching from lever filler to button filler. The Infrangibile was joined, starting from the second half of the 30s, by other two lines, called respectively Lusso and Impero. This last was the flagship model of the company and was produced in two versions, the rare multi-faceted Poligonale, and the round Trasparente. For these models, equipped with a special button filler akin to the Vacumatic, have been used the most beautiful semi-transparent celluloid.
