All [[Dunn]] fountain pens were produced using this particular filling system, which also characterized their style; the back of the pen, used as a knob of the [[stantuffo tuffante|pump filling system]] was carried out in red plastic (initially in hard rubber, then replaced by casein, a perishable and lower quality material), so it formed a distinctive feature of the pen, that in another slogan was described as ''"The fountain pen with the red pump handle"''.
