Conklin Duragraph Fountain Pen - Matte Black Demo (Limited Edition)
A Goulet exclusive! This limited edition Conklin Duragraph fountain pen features a transparent clear resin barrel, and a matte black cap. It is complemented with gunmetal trim and a matte black finial and grip section. Each pen is individually numbered on the cap.
It fills via standard international converter or short standard international ink cartridge (both are included).
This fountain pen is offered with your choice of a reliable, smooth-writing German made JoWo #6 steel nib in black, offered in sizes extra-fine, fine, medium, broad, or 1.1mm stub, or the new JoWo Omniflex flexible steel nib for variation in line width. With six nib options, you are sure to find a selection to fit your handwriting style.
Our note about the JoWo Omniflex nib: This flex nib will allow you to experience more bounce and softness than writing with conventional nibs. You can achieve some line variation with a little additional downward pressure, to a point. We recommend flexing the nib to about twice the line width that you would see without using any pressure. Please take care to avoid pressing too hard on the nib, as over-flexing could prevent the tines from returning fully to their original position and decrease or stop your ink flow.
The Duragraph draws its inspiration from the rich heritage of the Conklin brand, which was purchased and revived by Yafa in 2009. It is manufactured in Asia, assembled and distributed from Canoga Park, California, and pays tribute to its roots with a “Toledo, Ohio” engraving on its nib and barrel. The cap top is embellished with the Conklin Est. 1898 logo and the cap band are engraved with the famous Duragraph model script font with three Conklin Crescent logos on either side of the model name.
In 1923, the Duragraph model was launched, and shortly afterwards was considered to be "the definitive" pen. The model was named by combining the words, durable and graph - Duragraph. Created to last as an heirloom to serve many generations, the Duragraph is offered with a lifetime guarantee. In honor of the Duragraph's 91st birthday, Conklin has introduced a new Duragraph collection that brings a fresh, modern style to a timeless oversize flat top design. Crafted from quality hand made resins, the Duragraph is substantial in size, yet not so large to be unwieldy in the hand.
The Duragraph offers the ideal choice for your individual handwriting style. The cap top mounted clip allows the pen to sit low in the pocket, making this model a more practical choice for everyday use. Each Conklin fine writing instrument is housed in a luxury gift presentation box lined with rich satin. It comes with a converter and also accepts short standard international cartridges. Ideal as a perfect gift for yourself or a loved one, this model is the right size for both men and women who use fine writing instruments in their daily professional lives.

Customer Reviews
The body of the pen is pretty and and looks nice.
The clear part is not a polished translucent like you would expect from a TWSBI or other clear pens. It has a very slight frosting. If you're not picky like me, this won't bother you.
The pen writes extremely smooth, I inked it up with Diamine Ox Blood.
HOWEVER, I have the Fine nib and it writes quite broad in my opinion. Between my medium and broad TWSBI nibs. I'm very disappointed in this as I wanted this pen to be an actual nib. I can't imagine this is for any brand/country.
This pen writes as good as it looks. The weight and balance is perfect unposted. The case looks great on the desk. The ink flow is wonderful. I did order with the Omni flex nib. I filled it with Monteverde Midnight black and it really looks good when it’s inked up but i am curious and will try next refill how some thicker ink like my noodlers ink and will see how it goes. I could go on but to make it short and sweet I can not find a single thing to even think about complaining about
I really like this pen. I purchased the Omniflex. It gives my handwriting some character. This is a converter pen but looks like a demo piston. Wonder for the price.
As clear Demo's go, it is a good looking pen. Feels great in the hand and the extra fine nib writes smoother than many of the more expensive pens I own at 10 times the price. I had to go back into my records and see what I paid for it. I was shocked. It is an amazing pen at any price.
Honestly, I don't use my Duraflex pens much because I have so many other pens to use! So, I puled out one, inked it, and realized this is a gem of a model! This black pen was different and attractive. I like the satin (matte) finish of the cap and other black pieces on the pen. And the clear body was different. So I oirdered it with a medium nib. Those that I have are all broad nibs. Well, I inked it with Herbin Vert de Gris and WOW!!! I am really happy with this pen! First the pen is really handsome. That satin finish is smooth and had a dull shine, but is not shiny. It looks and feels great. And the clear barrel is somewhat unique. It looks nice. But the medium nib is fantastic! It is smooth and writes perfectly. It's not too dry, and not too wet. It's just right. I love this pen. The pen is comfortable. I tend to really like girthy pens. This pen is not too thick and not too thin. Overall, I guess this is the baby bear of pens. It's just right!
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!
