This is the classic fountain pen endorsed by Mark Twain for its mess-free ink reservoir that refills with the simple tap of a finger. First patented in 1897, the venerable Conklin design features a bladder filling system that is controlled by dunking the tip in an inkwell and depressing the rose-gold crescent on the barrel. This innovative mechanism eliminates the waste of disposable cartridges, as well as the mess and tedium of feeding ink into an old-fashioned pen with an eye dropper. Twain praised this convenience in an advertising campaign, and he raved that the protruding crescent and the cap’s rose-gold clip prevented the pen from rolling off a desk, making it a “profanity saver.” Perhaps the key to penning the next Tom Sawyer or The Adventures of Huckleberry Finn, the elegant instrument has a durable steel nib that enables smooth, continuous writing. 5 1/2" L x 1/2" Diam. (1 1/4 oz.)
