La Mer’s beautiful cerulean and azure gradient design stands as a tribute to the shifting, endless ebbs and flows of the tides of the sea. The gradient flows from a vibrant light blue at the cap, to a velvety dark blue, and lightens up to a serene light blue at the base of the pen.

Each writing instrument is crafted entirely at the S.T. Dupont factory in Faverges, France and is made utilizing ancient Japanese and Chinese lacquer techniques. Each pen passes through a two-stage production process. First, up to 9 Layers of sumptuous natural lacquer are hand painted to the brass barrel of each pen, the result is a pearl like shimmer and a luxurious finish that is resistant to shocks, scratches and even fire. Once this base lacquer is polished and prepared, the second stage involves spraying an additional pearlescent lacquer in small spurts to give the pens unique ‘gradient’ effect.

This iconic oversized S.T. Dupont pen features the bold Dupont 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. The cap comfortably posts on the back of the pen with a delicate ‘snap’. Each pen is presented in an S.T. Dupont gift box.

The fountain pen features S.T. Dupont’s 14kt gold nib in EF, F, M, and B nib widths and fills with the included cartridge or bottled ink using a converter.

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.

FAQs about Fountain Pens

How do I fill a fountain pen with ink? 8EDA1617-F73A-4DAF-8245-6D2BF4ABEB7B

It depends on the pen's filling mechanism, which you can find in the Technical Specs section above. 

Here's a quick definition of the most common filling mechanisms:

  • Cartridge - A 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! Check out our quick guide here.
  • Converter - 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. Here's a video for how to fill a cartridge/converter pen using a LAMY pen as an example.
  • Eyedropper - A pen that utilizes the entire barrel as a reservoir for ink. Ink is directly filled into the barrel, allowing for a high ink capacity. Here's a video on how to do it!
  • Piston - A type of filling system that uses a retracting plunger inside a sealed tube to draw ink into a pen. They are typically either twist or push-operated. These pens cannot accept cartridges or a converter, and only fill from bottled ink.
  • Vacuum - A push-style piston that uses pressure to fill the large pen body with ink. They seal the ink chamber when closed, making it ideal for flying without risk of leaking. Check out our video on how to use a vac filler here.

Check out more info on these filling mechanisms including a video on how to fill each one on our blog.

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

It depends on the filling mechanism, but it mostly comes down to flushing it out with water, and sometimes a little bit of Pen Flush if the ink is really stuck. 

It's a bit easier to show than to tell, so we've put together a few quick videos showing you the process:

How often do I need to clean my fountain pen? 8EDA1617-F73A-4DAF-8245-6D2BF4ABEB7B

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.

My pen won’t write! What do I do? 8EDA1617-F73A-4DAF-8245-6D2BF4ABEB7B

First things first... make sure you have ink in the pen! Be sure that the ink cartridge or converter is seated properly in the pen, and that you aren't out of ink.

We always recommend you give your pen a good cleaning first, using our Goulet Pen Flush, or a drop of dish soap in some water. New pens often have some machining oil residue left in the feed, so a good cleaning often does the trick first.

If that still doesn't work, try priming the feed. This consists of either dipping your pen nib and feed in ink, or forcing ink from the converter down into the feed. 

If it’s still not working after that, please reach out to us so we can help! 

What's your return policy? 8EDA1617-F73A-4DAF-8245-6D2BF4ABEB7B

You can submit a return request within 30 days of your order date. You can read all our Return Policies here.

To initiate a return, please submit a request at the Return Portal. Our Customer Care team might reach out to you for more information.

Please note we are unable to accept a return of any Namiki or Sailor Bespoke fountain pen for any reason once it has been used with ink. Please thoroughly inspect and dry test the pen before use.
