In [[1933]] was created a very special re-entrant nib mounted on a spring that was made by screwing the cap back by the pressure of an inner tip (see {{Cite patent|FR|737930}}). This system, along with the re-entrant nib, was used in the new model [[Stylomine 303B|303B]], produced in three versions corresponding to three different sizes. The loading was a refinement of the previous system of [[Stylomine 303|303]] and was also used for the model [[Stylomine 303C|303C]], without re-entrant nib, which in addition to the three previous versions was made in [[celluloid]] and with a fourth size, large enough to call it [[Mastodonte]].
