The Conklin Pen Company® is recognized as being one of the first companies to add the feature of true mobility to daily writing. Innovator Roy Conklin successfully created the first self-filling fountain pen, promoted as “a fountain pen that has its own stomach,” which became much loved by renowned American author Mark Twain. In 1923, the Duragraph™ model was launched, and shortly afterward was considered to be 'the definitive' pen. The model was named by combining the words, durable and graph to equal Duragraph. Created to last as an heirloom to serve many generations, the Duragraph™ is offered with a lifetime guarantee, and brings a fresh, modern style to the timeless oversize flat top design. Crafted from quality handmade resins, the Duragraph™ is substantial in size, yet not so large to be unwieldy in the hand.
