[[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. It is also mentioned a [[Perfecta]] model, produced in the early 20s, with [[torsion filler]] that is the first example of automatic filling.

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]].
