Conklin Duragraph Ballpoint Orange NightsHeritage In 1923, the original Conklin Duragraph was named by combining the words, durable and graph and quickly became one of Conklins most essential designs. The new Nights collection brings that classic sensibility to the modern era with a stunning, yet highly affordable design in either Orange, Purple or Red. Crafted from quality handmade resins, the Duragraph is substantial in size, yet not so large to be unwieldy in the hand. Overall Size 5 1 2
