This iridescent purple resin Magnum fountain pen is one of Diplomat’s most affordable offerings. The special no-slip lacquer gives the body a soft touch, and it has a black ergonomic grip section.

It comes equipped with a smooth writing JoWo stainless steel nib, chrome trim, and fills via standard international cartridge/converter (both are included).

This color is a Goulet exclusive in the USA. Please note that it may say "John Doe" on the outer box label as this is how the color is known outside the US.

Note: The Diplomat Magnum is gradually transitioning from matte to polished nibs. What you receive may be different than what is pictured here.

Diplomat Magnum (EF nib)

EF nib is very scratchy (very!). Did not enjoy using it at all. It was a major disappointment. I would never recommend this pen to anyone. After using it a couple of times, I cleaned out the pen and put it away.

This is my first fountain pen. It writes very well. My only complaint is that the grip is very narrow.

Nib: 10, Looks: 3

First impression out of box was this feels like a pretty cheap pen. Then I inked it.....hmmm. Well that was a surprise. What a great writing experience. (Pilot Iroshizuku Take-Sumi / F nib). The grip is smaller than what is comfortable for longer writing sessions for me, but I think I'll keep this handy for jotting notes, or maybe for shimmer inks. Overall pleased with this rather impulsive selection.

Lovely pen

I bought this as my first fountain pen. It was very easy to figure out how to fill the converter, and it writes beautifully. I had a couple of false starts getting the ink to flow, but I'm chalking that up to new user error, and I haven't had any problems with it since. It even matches the water bottle on my desk at work!

Fantastic writing - smooth as butter

The iridescent purple coloring is pretty, but not as intense as I had hoped. However, the writing experience is absolutely fantastic: the ink flows smoothly and glides as smoothly across the paper as any pen I have. Highly recommended!

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

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.
