Conklin are famed for their innovative crescent filler fountain pen. It is recognized as the world's first practical self-filling fountain pen, with an integrated converter that sucks the ink up via the nib. In 1903 Mark Twain, the iconic American author, expressed his preference for this pen. The Duragraph and All-American range offer an affordable option in marbled resin. Choose from medium, fine, stub nib. All Conklin fountains come with a converter and take standard international cartridges.
