The Conklin Duragraph Fountain Pen - Cracked Ice. Originally launched in 1923, The Conklin Duragraph ballpoint pen is considered as “definitive” pen. The name is derived from the amalgamation of the words durable and graph. The new Duragraph collection adds a fresh and contented flat-top design. The band of the cap is featured with Duragraph script logo and three Conklin Crescent logos on both sides.
