Initially the [[Dunn]] pens were made in hard rubber and were of good quality; the company distinguished itself by an extensive advertising campaign. The pump mechanism was simple and robust, and the pens were produced in a variety of models from small pens for women's to the [[Dreadnaught]] giant model (produced also in regular dimensions). An interesting feature, from a technical point of view, was also the introduction of a the caps composed by two parts, whose top section could be unscrew in order to discover the nib, but leaving it shielded by a protective cage in order to consent to fill the pen without pressing dangerously the nib on the bottom of the ink bottle.
