A timeless American innovation, the Conklin Mark Twain Crescent Filler Fountain Pen in Black Chase with Rose Gold Trim continues the legacy of one of the earliest self-filling fountain pens. First patented in 1897 by Roy Conklin in Toledo, Ohio, the Crescent Filler™ gained iconic status thanks to its revolutionary design—and the endorsement of literary legend Mark Twain.
This model features a textured black resin barrel accented with warm rose gold trim and the famous spring-loaded rocker clip, originally patented in 1916. The crescent filling mechanism remains fully functional and intuitive, offering a classic in-hand experience rarely seen in modern pens. Mark Twain’s signature is engraved along the cap band as a nod to the pen’s literary heritage.
Each pen is fitted with a JoWo steel cushion point nib, available in Extra Fine, Fine, Medium, Broad, Stub, or Omniflex. The Black Chase finish offers a refined, modern interpretation of a classic design.
