S.T. Dupont is renowned worldwide for crafting exceptional writing instruments of superior quality and design. The new ‘Fire-head’ guilloche is no exception and demonstrates one of S.T. Dupont’s oldest and most treasured crafting techniques 'guilloche under lacquer'. S.T. Dupont’s iconic ‘Fire-head’ guilloche pays tribute to the much celebrated ‘Louvre’ museum in Paris, France, famed for its glass ‘pyramid’ entrance, which serves as the design inspiration.

Guilloche is an intricate decorative technique created by engraving a surface with great precision and then adding a transparent layer of resin, enamel, or in the case of S.T. Dupont’s fine writing instruments, a natural lacquer over the engraved surface. S.T. Dupont engineers engrave a series of ‘pyramids’ throughout the barrel and cap of each pen using an ‘engine turning’ process that engraves very precise and intricate geometric patterns into an underlying material.

S.T. Dupont's artisans then add layers of natural lacquer to the solid brass engraved pen in a month's long process. Many layers of application and polishing impart depth and mystery to each finish, resulting in a smooth, unique texture on the surface. The engraved guilloche reflects light through the overlay of natural lacquer, creating a spectacular three dimensional display of color.

The Firehead Guilloche collection is launched on the Line D Large pen; recently remodeled with a new bold blazon on the articulated clip, 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. This graphite gray colored fountain pen is accented with matte black trim and a black plated 14t gold nib and fills via cartridge/converter (included).

Each fountain pen receives over 150 handcrafted operations and controls to ensure writing perfection. The fountain pen features S.T. Dupont's famous 'click' to echo their famous lighter 'cling'. 

With the natural lacquer exclusive patina effect, each piece is one of a kind. While the procedure remains the same, the result is always different. Depending on the color contrasts obtained, the handmade production process gives the product its very own depth and soul.

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.
