In keeping with S.T. Dupont's enviable reputation for luxury writing instruments at the forefront of technology, Dupont’s new 'carbon' collection combines all the unique benefits of modern day carbon graphite with S.T. Dupont’s iconic ‘Line D’ oversize writing instrument. This highly reflective carbon material is complemented by a bold matte black finish.

S.T. Dupont utilizes a specialized carbon graphite composite, a material synonymous with luxury, used in the production of modern day 'super' cars and rare mechanical timepieces. The final result is ultra-lightweight, corrosion-resistant, and aesthetically pleasing.

The Carbon Graphite collection is crafted in S.T. Dupont’s ‘oversize’ Line D writing instrument. Each pen features Dupont’s bold blazon on the articulated clip in black enamel, an enhanced Dupont 'D' in the crown of the cap and a perfectly balanced shape for exceptional writing. The pen cap closes with Dupont's iconic 'cling' and features a fluted grip section for a superb writing experience.

Perfectly engraved into each pen cap is Dupont’s iconic 'micro diamond head' design, emboldened with a matte black finish, perfectly accenting the vibrant colors of the carbon composite.

This blue and black carbon graphite fountain pen is complemented by matte black PVD and ruthenium trim. It is enhanced with a black 14kt gold nib, and fills via standard international cartridge/converter (both are included).

We do our best to photograph the pens to show how they will appear in person, but due to the nature of the material, there will be some variation in the pattern seen here. This adds an element of uniqueness to the pen, with no two patterns being exactly the same. We cannot honor special requests.


Company Background:

S.T. Dupont is a leading brand of luxury products designed and made in France. Founded in Paris in 1847 by its namesake Simon Tissot Dupont, today S.T. Dupont is world famous for their exceptional writing instruments. S.T. Dupont has been a supplier to Royals, Aristocracy and celebrities including: Coco Chanel, Leonardo DiCaprio, the British royal family, Audrey Hepburn, and Marilyn Monroe.

In the 1930s, S.T. Dupont perfected the bonding of the nigh indestructible Urushi lacquer onto metal, offering a strong luxurious finish to their writing instruments. The company mastered the art of fine lacquer by rediscovering and perfecting ancient Japanese and Chinese techniques. This process has become a staple of the luxury S.T. Dupont brand through the present day.

S.T. Dupont products are still made at the original workshop located in Faverges near the French Alps. Their writing instruments are world renowned for precise engineering and intricate goldsmith manufacture. They are committed to innovation and cutting-edge technology while also retaining status as a Heritage brand.

Frequently Asked Questions

How do I use this pen with ink cartridges? 8EDA1617-F73A-4DAF-8245-6D2BF4ABEB7B

A cartridge is small, disposable, sealed plastic reservoir that holds fountain pen ink. These come pre-filled with ink, and typically you just push to insert them into place and you'll be ready to write!

This pen uses standard international ink cartridges, a common size which is available in many colors from various brands.

You can learn more about how to actually install an ink cartridge on our blog, or in this video tutorial:

How do I use a converter? 8EDA1617-F73A-4DAF-8245-6D2BF4ABEB7B

A converter goes in the place of where the ink cartridge would normally go. From there, you can fill your fountain pen from bottled ink.

A converter is a detachable and refillable ink reservoir that allows you to use bottled ink in a cartridge-accepting pen. Typically you will install the converter into the grip section, dip the nib/feed into the ink, and twist or pull the converter knob to draw ink into the converter.

We have a great video showing how to use a converter here:

How do I clean this fountain pen? 8EDA1617-F73A-4DAF-8245-6D2BF4ABEB7B

It mostly comes down to flushing out the pen with water, and sometimes a little bit of pen flush if the ink is really stuck. 

We put together a blog post with step-by-step instructions, or you can watch the video here:

We recommend a good cleaning every 2 weeks, and any time you change ink colors. Water will usually do the trick, but we recommend you use our Goulet Pen Flush if the ink has been left in the pen for a while and could have dried up, or when you’re switching ink colors.

For even more information about fountain pen cleaning, check out our Fountain Pen 101 video blog post.
