The ''safety filler'' was born in the United States in the last decade of 1800, although it is not possible to define precisely an inventor, it is attributed if not the invention at least the massive introduction on the market to [[Waterman]], which was the main U.S. manufacturer to adopt it on a large scale.<ref>But the company has done so using many patents of ''Francis C. Brown'', of [[Caw's]]</ref> However, it has had a much greater success in Europe, where at the beginning of the century practically all the producers (and in particular the German ones, among which the [[Kaweco]] stands out, who also made some developments) made use of this system, and where it has remained in production much longer.

Although it is classified, perhaps unjustly, among the primitive loading systems, in reality the ''safety filler'' has resisted on the market much longer than other filling systems created in later periods. In particular, in Europe there are mass-produced models that use it until the 20s and 30s. Because of its historical value, which sees it as substantially the first mechanical system dedicated to filling the pen, it continues to receive an undeniable interest from collectors, many of whom have a particular preference for [[safety]] pens.<noinclude>
