To celebrate the brand's 100th anniversary, Diplomat has drawn inspiration from both the past and the future for its new fountain pen: Nexus.

Based on piston technology, an invention described by pen enthusiasts as revolutionary at the start of the 20th century, but combining it with a new patented sealing system by securely sealing the cap, Nexus combines the best of yesterday and tomorrow. No more risk of running out of ink; no more cartridges and their plastic packaging.

This black anodized aluminum fountain pen is accompanied by silver trim. It has an ink window in the barrel so you can visibly see your remaining ink level. This pen is equipped with a smooth-writing #6 size steel nib made by JoWo.

To fill this pen, hold it with the nib facing upwards. Simply unscrew the barrel from the nib/grip section, fill the barrel with your preferred bottled ink using the included eyedropper or an ink syringe, and screw the nib/grip section back on.

The patented automatic closing sealing system works by screwing on the cap, which activates a secure seal. No more risk of ink leaking into your cap when not in use!

Thanks to its unique characteristics - a proven seal, no risk of leakage even on an airplane, a large ink capacity, ease of use, and perfect fluidity of writing - Nexus offers a reassuring and infinite writing experience.

A bottle of black Diplomat ink is included.

A Great Pen

I have received this pen and I find that it is wonderful to write with. One bit of advice, don't over fill the pen. I found that when I did, I got ink seepage between the nib unit and the body of the pen.
After I emptied out some of the ink the problem went away.

Amazing Writer

I would like to thank the Goulet team for providing me a writing sample of this pen. When I received this beauty I was in love. I used it as a dip pen for about a week so I could experience it using different colors. This No. 6 steel nib holds ink as a dip pen quick well.After I decided to ink this pen it has been an absolute joy to write with. Also, the ink capacity goes for ever.

Enjoy This One So Much That I Might Need the Blue One as Well!

This pen is a phenomenal writer, and it's everything I enjoy in a fountain pen: meticulous detail all around, a new mechanism, and I love that it can be taken on a plane without issue thanks to its ability to completely seal off the ink chamber when capped. I would recommend this one for anyone who enjoys a slightly heavier pen. The Fine nib is entirely smooth, and lays down a dependable line every time with no hard starts. I love this one.

I purchased the pen for my wife at Christmas. She has a number of your pens and loves them.

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.
