Delta 39+1 Fountain Pen (Limited Edition)
Delta is back, with a brand new limited edition fountain pen in celebration of the 40th anniversary of the founding of the Delta Pen Company!
The new "39+1" collection is a limited edition of only 399 individually numbered pieces. This fountain pen is made of a rare celluloid, impossible to reproduce today. This mottled black and brown celluloid was previously used to make the Delta Enrico Caruso limited edition. The barrel and cap are highly polished, and the pen is complemented by gold vermeil trim (gold over sterling silver).
The pen fills via standard international cartridge/converter (included), and is also eyedropper fillable.
A new patented feature is the Write Balance system. Within the threaded cone at the barrel end of the fountain pen is a gold-plated 2-gram removable weight. You can keep it inserted into this cone for a more back-weighted pen, or you can remove it to shift the pen's balance more towards the front. A back-weighted pen allows you more control of the fountain pen's movements which is ideal for calligraphers and letters, while a front-weighted pen allows the pen to do more of the work which is ideal for longer or casual writing sessions.
A variety of nibs are available for this pen, including 18k gold nibs and 14k flexible gold nibs all made by JoWo, each engraved with the Delta signature logo.
The barrel features a deeply curved grip section leading into gold-plated threading. From there, the barrel flares into a rounded body that feels substantial in the hand, ending in the severe conical blind cap that contains the two-gram Weight Balance. The straight-bodied cap ends in a taper, a common element of Italian pen design.
A single gold-plated barrel ring toward the section marks the place where the barrel twists off for cartridge and converter filling, or to fill the entire barrel with an eyedropper, and a gold band at the conical tip is engraved with the edition number. The gold-plated roller clip features DELTA logo engraving, and a gold-plated cap band features elegant scrollwork.
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.

FAQs about Fountain Pens
How do I fill a fountain pen with ink?
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?
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?
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?
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!
