The Line D Collection is defined by signature features that signify S.T. Dupont’s strong history. The pens feature Dupont’s famous ‘cling’ sound when opening and closing the cap of the pen, the blazon signature can be found on the articulated clip – a symbol of 145 years of pride and family story, and the signature cursive letter “D” at the top of the cap has been redesigned and magnified for immediate recognition. The curved shape and soft lines of the Line D collection provide a timeless elegance with a well-balanced design to provide the ultimate writing comfort. Dupont offers the best durability as the pens are hand-crafted in France from solid brass and accented by precious materials – palladium, gold, and natural Urushi lacquer for a luxurious finish.
