The S.T. Dupont Line D Medium Blue Guilloch fountain pen combines classic styling with the best of modern engineering. Meticulous machine engraving and hand assembled components combine to create a writing instrument of enduring beauty and reliability.

Our complimentary nib tuning ensures that your S.T. Dupont fountain pen will have writing qualities equal to its appearance, and these 14k nibs also make an excellent starting point for many of our exclusive nib customizations – choose the Fine or Extra Fine for best results with added Flex, or the Broad for our noted Architects Point modification.

The Line D Medium series provides a surprisingly affordable introduction to the luxury fountain pens offered by S.T. Dupont. Each pen is hand assembled in France using the highest standards of craftsmanship.

The pen can fill with any bottled fountain pen ink when fitted with the provided converter, and can also also use convenient international size disposable ink cartridges, such as those we offer from Pelikan. A stylish presentation box includes the pen, converter, and starter pack of cartridges. We are an authorized S.T. Dupont retailer.
