Advanced for its time and featuring a reliable method for filling ink, the Conklin Crescent Filler® attracted attention from many prominent figures of its time. In 1903, renowned American author and humorist, Mark Twain, became the official spokesman for the Conklin® brand. In celebration of Conklin's innovative design and Twain's passion for the fountain pen, the Mark Twain Crescent Filler® is now available in a new finish featuring gunmetal plating over solid brass.
Each Crescent Filler utilizes Conklin’s groundbreaking original design, one that still works as effortlessly as it did a century ago. Crafted from metal, this limited edition pen is a beauty to behold and is tastefully engraved with Mark Twain’s signature along the band. Each pen still maintains the original Conklin® spring loaded rocker clip that was patented in 1916, the perfect addition to any pocket, jacket, or coat.
This fountain pen is offered with your choice of a reliable, smooth-writing German made JoWo #6 steel nib in extra-fine, fine, medium, broad, or 1.1mm stub, or the new JoWo Omniflex flexible steel nib for variation in line width. With six nib options, you are sure to find a selection to fit your handwriting style.
Our note about the JoWo Omniflex nib: This flex nib will allow you to experience more bounce and softness than writing with conventional nibs. You can achieve some line variation with a little additional downward pressure, to a point. We recommend flexing the nib to about twice the line width that you would see without using any pressure. Please take care to avoid pressing too hard on the nib, as over-flexing could prevent the tines from returning fully to their original position and decrease or stop your ink flow.
Limited to 1898 worldwide.
