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/black marbled hard rubber. It was relevant also for the production of [[overlay]]s in both rolled gold or precious metals. But in this period the most characterizing product for the company production was the ''Autostyl'' mechanical pencil, in which the mine is automatically replaced after exhaustion. The production of mechanical pencils continued for all following years, with different names such as ''Stylomine Automatic'' and ''Stylomine 202''.
