This Delta Duna fountain pen has a simple yet elegant design. It has a vintage-modern style with a classical ball clip and conical tip. The Duna features a piston-filling mechanism with a yellow-tinted ink window that enables you to keep track of your ink level. The cap's tapering shape emphasizes its graceful silhouette, while the high-quality Italian resin features a marbled pattern that exudes a Mediterranean charm.

This swirly semi-translucent yellow and turquoise pen is accented by gold-plated trim and a gold-plated steel nib. The stainless steel #6 fountain pen nib is made by the German brand JoWo. In addition to several standard nib sizes, there is also a flex nib variant that allows you to alter the line thickness by varying the pressure applied to the nib.

Delta, the renowned Italian pen brand that has been creating stunning and distinct pens since the 1980s, has made a triumphant return after it ceased operations in the 2010s. This new Delta brand has been personally revitalized by Nino Marino, one of Delta's co-founders who also owns and manages Maiora and Nettuno pen brands. Each pen is handmade in Naples, Italy, and is individually numbered.

We do our best to photograph the pens to show how they will appear in person, but due to the nature of the material, there will be some variation in the pattern seen here. This adds an element of uniqueness to the pen, with no two patterns being exactly the same. We cannot honor special requests.

Stunning beautiful!

Excellent. This pen is gorgeous. I filled it with Colorverse Ham #65, Glistening Series, which is a teal color that matched the teal in the pen. The pen flowed like silk across the page. The color was perfect! I'm in love with my Italian! Highly recommended

Love the pen. Beautiful to look at, and writes great. Although others have said, they had issues with filling, I had none. No fuss, no mess. Filled the pen with the turquoise ink, which looks great with the color on the outside, and seems like magic when I write. Looks like the Incas truly flowing out of the color of the pen. I will say it's a generous medium nib. Almost makes me wish I had ordered fine.

BEAUTIFUL but...

I purchased the Delta Duna in Horizon Yellow with the extra fine nib. This is a very popular color and EF was all they had left. Have no doubt, this pen is gorgeous! The packaging is beautiful, the pan has wonderful balance and a great hand feel. Unfortunately, my praises end there. Right out of the package the cap had a sticky film on it like glue left behind from a sticker. After polishing the cap, I tried to fill the pen using an ink sample. The grip is too large to get into the bottle for a decent fill. That is no big deal, I have other inks in larger bottles and decided to clean the pen and try again. After only one partial fill, ink has gotten on the back side of the gasket. I took my time and thoroughly cleaned the pen but was never able to get the ink on the back side of the gasket to disappear completely. I filled the pen with Farris Wheel Press Peter Moss, admittedly a dry ink. The combination of that ink and the extra fine nib makes the writing experience horrendous. I own other pens with EF nibs, so this is not a lack of experience writing with that size nib. The feedback is cringe worthy and on the up strokes it feels like I'm going to tear the paper. I have been writing with this pen for the past few days and find if I use a feather touch it is almost bearable. When the ink runs out (maybe sooner) I will fill the pen with an ink that flows a little wetter and hope for a better writing experience. If I could go back I would wait until the larger nib sizes were available for purchase. I'm not happy with the nib but I am most disappointed by the filling mechanism and for that reason I have given this pen a lower rating.

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.
