This safety feature was a big step forward at a time when ink leaks were very common, and the holding of the caps, often simply locked by pressure on the pen barrel, was very problematic. From this point of view, pens [[safety]] remain superior to any modern pen. Moreover, the hermetic closure of the cap, which also includes the nib assembly, allows to reduce to practically zero the possibility of evaporation of the ink, which is very difficult to dry inside the pen, thus allowing the use of inks much thicker than the ordinary ones. For these peculiar characteristics [[Waterman]] has continued to produce a line of these pens, aimed at artists and musicians and aviators, until the early '40s.
