This dark blue 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).

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

Good pen, writes well.

Easy to fill, smooth writing, just a little lite for my hand, feels like it needs some weight to it. But that's a small complaint for the price and use of the pen.

Great little pen - after some adjustments

I bought this pen with a M nib over 3 years ago and am only just now getting around to reviewing it. The reason? When it arrived, it barely wrote - lots of skipping and hard-starting. I was new to fountain pens, so I had no idea what was wrong. (I should have contacted customer service back then, but I was frustrated enough that I didn't think of it.)Since then, I've gained some experience with pen repair and figured out that the tines were spread way too far apart. I narrowed the slit, and now this is the pen I was expecting years ago - the nib is smooth and consistent with just a little bit of bounce, and the Magnum's light weight makes for fatigue-free writingI rate the value as high because it really is a good value if you get one that's tuned correctly from the start. As for quality, well, it looks nice, but the most important part was flawed, so I can't go higher than medium there.

A fine pen!

I ordered this pen after a comment Drew made about it in one of his videos. He mentioned that it has a surprisingly soft nib. I was intrigued. And, he is right -- it does indeed. It is a nice nib and a smooth one, but my pressure must vary too much as I write because some strokes would be light and others darker. Interesting, but not my jam. In blog post, it was mentioned that the Goulet #5 nib fits a Diplomat Magnum. I have 2 of the Goulet #6 nibs on 2 Jinhao pens and I like them a lot. So I ordered a 1.1 Goulet #5 nib, put it into my Magnum and love it! It writes so nicely that I am reaching for it a lot. The Indigo Blue color is nice and I think it's a good pen to keep inked up with blue ink. Currently it has the blue cartridge that came with it. Next, I'll try the converter that also came with the pen and see how a more royal blue ink will look. The pen is lightweight, but very comfortable in my hand. Good purchase!

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

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.
