The [[Modelli iniziali Tibaldi|first produced models]] were black hard rubber [[safety]] pens, both plain and  with metal [[overlay]]. Among these there were a special ''doctor's pen'' model that like the [[Omas]] one contained a thermometer inside the barrel. ''Tibaldi'' safeties remained in production with various modifications of the [[fall]] of ''Tibaldi'' until the 40s. But the most interesting in the early ones was the [[Perfecta]] model, produced in the early 20s, with a [[torsion filler]] and a  complex safety system as the first example of automatic filling fountain pen.

In this initial period, following a strategy adopted by many Italian producers, ''Tibaldi'' used an alternative mark, ''"The GTB Pen London"'', that following the xenophilous trends was masquerading itself as Anglo-Saxon company. With this mark were produced second tier pens, substantially identical, apart from the finish of the cap top and the knurls of the bottom, to the production marked ''Tibaldi''.
