The success of the Duofold, despite its price (10 dollars) was high for the time, continued for over a decade in which the models were revised several times, adjusting the production to the introduction of new materials such as celluloid or the new Streamlined style with tapered models. In 1923 was opened a plant in Canada, and was introduced a Lady Duofold model for women. In 1926 also the Parker began to move production from hard rubber to celluloid.
