Noodler's Konrad Flex Fountain Pen - Clear

The Konrad flex pen was introduced in early 2012 - it is smaller than the Ahab, but larger than the Nib Creaper. It features a steel flexible nib and a twist piston mechanism with a blind cap. The Konrad is made of a celluloid derivative and is technically biodegradable and formed from a "renewable resource". The vegetal resin body of this pen may show particles or striations within the material. This is most noticeable in demonstrators and bright colors.

The Noodler's flex pens were designed for the hands-on tinkerer - they are made to be taken apart and adjusted. The nib and feed pull right out and can be adjusted and heat set for optimal performance. Don't be afraid to get a little ink on your fingers while you learn how to use this pen.

As a simple rule of thumb for writing with a flex pen, just apply slight pressure on your downstrokes, which will spread the tines and increase the line width, achieving that optimal line variation. Make sure to go slowly so that the ink can keep up with your writing. As with any flex pen, it just takes practice!

Due to the residual machining oils used when cutting the feeds for these pens, we highly encourage you to give the pen a good flush before use. We recommend any of the following options: distilled water, water with a touch of dish soap, a pre-packaged pen flush, or a solution of 10% clear ammonia to water. This should resolve most ink flow issues!

While these nibs are #6 size, these Konrad pens do not accept other brands of nibs due to the shape of the interior grip.

Noodler's Konrad Flex Fountain Pen - Clear is rated 4.119 out of 5 by 84.
Rated 5 out of 5 by from Amazing for $20. I've been writing with fountain pens for many year, but because my writing is just utilitarian I never tried a flex pen. At $20 it was hard not to give it a try. The flex works, and I was able to get variable width lines from it without much problem. It'll take me some practice to really get distinguished lines from this after spending all that time (and miles of ink) writing with a non-flex nib. On the plus side any #6 nib fits, and can easily be mated to the feed. That's really an understated selling point, so I'll repeat it. ANY #6 nib will fit in this thing. I've tried several and they all work well with the supplied feed after setting.

Rated 2 out of 5 by from Fragile Piston I guess the piston mechanism must be the weak point of this pen, because my first Konrad arrived with a broken piston and the piston of my second just broke. I'd only had it four months, and I'd used it gently. And, of course, it's just a piece of plastic, so although I can remove the broken piece, I can't repair it--and I haven't found any source of replacement pistons. Other than that I love the pen. If I could buy replacement pistons, I'd keep two or three spares on hand and this would be my favorite pen. As it is, I guess I'm going to have to go back to other pens. :( I hope someday Nathan sells replacement Konrad pistons and the Goulet Pen Company stocks them.

Rated 4 out of 5 by from Slightly better than Ahab, in my experience The nib and feed are identical to those of my Ahab, and the piston mechanism seems no better nor worse than the Ahab's home-made-looking, but sturdy and reliable plunger. I do appreciate that the screw knob under the blind cap doesn't change position as I change the reservoir's volume, allowing me to keep the air ratio down to prevent blobbing due to thermal expansion, without altering the pen's external profile. The clip is a bit better executed than Ahab's ambitious whale, its edges nicely turned under and its spring action pleasantly firm. I also find the cylindrical grip section to be a bit more comfortable than Ahab's rounded step-downs. I might have to grab another one in that blue demonstrator style...

Rated 5 out of 5 by from Received one for Christmas I received one of these pens for Cristmas, and I have to say that it is an excellent pen so far. It writes well and flexes really well also. I have found that it lays down ink more consistently than the Noodler's Nib Creaper flex pen, but doesn't flex quite as much. To me, this is an adequate trade off. It's also a bit thicker, which is good as I found the Nib Creaper a little uncomfortable for extended periods of flex writing with its smaller diameter section. The Konrad isn't too big though, which is nice for me. I have slightly smaller hands and I like to post my pens. Pens that are too big to be posted are uncomfortable for me. Overall: Excellent pen.

Rated 4 out of 5 by from Worth what you pay. A very nice inexpensive piston filler. However I have a few gripes: -the smell, this pen stinks! When I first opened to box I was over come with a nauseating smell of something reminding me of vomit. It isn't as bad now but still a bit off putting. -staining, the ink I use stained the inside of the pen slightly (lamy black) doesn't really bother me. But it might you. - blind cap, don't screw the blind cap on too tight or you'll unscrew the piston! I put silicone grease on the blind cap threads to help this not be an issue. --- Overall, for twenty dollars it's not a bad pen. I think I may replace the nib with an italic goulet nib and maybe it will become a daily writer!

Rated 5 out of 5 by from Yes, yes, yes! This is the pen I keep returning to. The fact that at $20, you get a reliable pen with a sturdy body, a flex nib that is easily replaceable.. wow. Perfect size, weight and balance. Even the clear Konrad looks classy enough that I've gotten compliments on it. It's so evidently a fountain pen that it starts a lot of conversations. This fountain pen can be completely disassembled. When you change inks, you can literally turn this pen back to brand-new. The nib can be swapped for the Goulet nibs, which are some of the best nibs on the market. My medium Goulet nib + Konrad + Rhodia = best fountain pen experience possible for the money. I understand if people don't like them, but don't say "Avoid these pens!" Just because you can't get your one pen to work, doesn't mean they're all junk. Mine is better than my TWSBI, in my opinion. The question is, should I buy a really expensive pen, or a bunch of Noodler's pens? Hm... that's really something to think about.

Rated 5 out of 5 by from Noodler's Konrad Flex Nib Piston Fill Fountain Pen After buying my 4th Ahab, I thought that the Konrad could not be missing from my collection. After a super fast delivery (as it always happens with Goulet pens) all the way from the US to Greece, I finally got the Konrad in my hands. This is a very nice clear demonstrator, smaller than the massive Ahab, but suited for most hand-sizes, I guess, and with a piston mechanism that more expensive fountain pens would be jealous of. I use it mostly not as a flex pen, but with KNOX or Bulow nibs that fit perfectly. The feed allows a rich, wet flow of ink and the whole thing just works fine. The fact that you can take it apart entirely, makes cleaning a piece of cake, and allows for other nibs to be used on it, fact that every fountain pen lover enormously appreciates. I love it, and use it often along with my Ahabs.

Rated 5 out of 5 by from not for the begginer This is a very cheap and interesting pen. But out of the box it?s rubbish, needs a lot of work to get it to work properly. But after I spent some ( a LOT of) time tinkering with it I fell in love with it, and carry it everywhere. Great introduction to flex fountain pens if you are willing to adjust and play with it. Made the "Ease my flex mod" on all of them and now they are pretty close to my vintage flex fountain pens. Highly recommended if you are willing to spend time tinkering with it.
