Parker Duofold Fountain Pens

“Duo” was a word which was common in marketing circles of the time and the modern equivalent would be “mega”. It sought to connote the excellence of the Duofold over it’s market competitors and was a big pen in many ways(price wise and size wise at 5.5 inches for the original Senior Duofold)

The Duofold was made from a shiny hard rubber which was followed in 1926 when Parker introduced the Duofold made with an “unbreakable Permanite” which was a type of plastic made by DuPont for Parker.
