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 [[Tibaldi Lusso|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 '' [[Tibaldi Trasparente|Trasparente]]''. For these models, equipped with a special button filler akin to the ''[[Vacumatic filler|Vacumatic]]'', have been used the most beautiful semi-transparent celluloid.
