Review: Great tinker-friendly fountain pen with a flexible extra-fine nib - I really like this pen. The nib is the only truly extra fine and flexible nib I have ever found in a fountain pen. The lines it makes have a definite thick-and-thin quality that I haven't seen from any other fountain pen. I can write at full speed with it. The pen comes completely apart very easily, which means that for better and for worse it's adjustable. So if the ink is flowing to fast or too slow, you may need to fiddle with it -- Noodler's designs these pens to be inexpensive and tinker-friendly. It's a good size, not too big or too small. It holds a lot of ink. The plastic it's made from is kind of soft and does smell peculiar, but that's intentional, as Noodler's makes these pens from environmentally friendly materials.
Review: I Like It For Writing Block Letters - I bought the Konrad because it was inexpensive, and I wanted to try it with my own Spencerian-styled round hand. The nib is what I would call Fine, and the fat barrel is comfortable in my big hand with extra-long fingers. However, because the nib is Fine, is squared-off at the tip, and is somewhat less flexible than what I am used to, it requires a little more practice to achieve a smooth line, especially since I lean my letters forward at a significant angle. I think that if I keep at it, eventually I WILL get those smooth lines. Your results may vary. Now, I mentioned that I write in a Spencerian style with a forward-leaning angle, but I did try the Konrad in a vertical cursive hand and a block-lettered hand. In those applications, I think it excels. In fact, I think the Konrad writing experience looks and feels exactly like a German brand whose name rhymes with hammy and begins with an “L.” The Konrad is an excellent starter pen, but it’s also an excellent pen for those who like to write in a particular style of round hand. Most importantly, you have to be OK with the interesting off-gassing that comes from the plastic these pens are made of. My untrained nose detects hints of fresh clay, new racquet balls, Godzilla-sized toe jam, formaldehyde, and ghee butter. Yes, that’s what I smell. And from what I hear online, the smell does not go away. Luckily, you can’t smell it unless you put the pen or your fingers right up to your nose. And by the way, the smell doesn’t stay on your fingers for long. I don’t mind it, but then I have an indoor dog.

## Questions & Answers

**Q: Does it come with ink in it or do I need to buy the bottle?**
A: You need to buy bottled ink. (This pen does not work with cartridges, as some fountain pens do.)  You can buy samples to see what u like. THERE ARE SO MANY COLORS TO CHOOSE FROM - Samples can be between $1-$3  each for 3-5 ml which can fill your pen a few times. Since it's a flex nib it's great with shading and/or sheening ink. It's also good to look into fountain pen friendly papers such as Rhoda, or Clairfontaine or if you want to go all out and see what this pen can do, Tomoe River Paper. For samples selection, Gouletpens.com is great!

**Q: Can you use an ink cartridge?**
A: No, piston fill only.

**Q: Does the demonstrator Konrad come with a spare (non-flex) nib?**
A: No, mine did not come with a spare nib.

**Q: Hello , What is the nib size of the pen?**
A: The Konrad has a #6 nib, just like the Ahab. I have swapped other #6 nibs and they work well.

### ⭐⭐⭐⭐⭐ Works as expected
*by R***S on November 7, 2025*

Great pen. Smells awful though. I understand and appreciate that they used some bio-friendly resin, but it takes a bit of getting used to. I washed out the pen after I emptied the initial bit of ink I filled it with, and that seemed to tone down the smell. The pen itself writes great, but it does take a bit of pressure for the little bit of flex I'm able to get. It does make a difference, though. Since I primarily purchased it for drawing it works fine for me. I do think, however, that it makes a good writing pen as well. The writing is pretty smooth with no pressure. The pen has a good weight and feels comfortable in my hand. Easy to clean and maintain, it is but together well and should last a long time.
