Noodler's Konrad Flex Fountain Pen - Amazon Pearl

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 #6 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 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 for optimal performance. Don't be afraid to get a little ink on your fingers while you learn how to use this pen. We recommend watching our video (below) to see how heat-setting the nib/feed can help improve flow issues.

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!

Noodler's Konrad Flex Fountain Pen - Amazon Pearl is rated 3.875 out of 5 by 8.
Rated 2 out of 5 by from Cool pen, not super durable. I got this pen, inked it up, and had a ton of fun doodling and writing "hello" repeatedly. After 30 minutes or so, I heard a little pop noise, and the section had developed a small crack. Nothing huge, but now ink sort of seeps out around the feed. The pen is still functional otherwise, but I have a feeling the crack will grow, as cracks are wont to do. Ah well. The pen looks cool, I love the piston filling, and I think that the basic cleaning/maintenance of the pen is really simple, which is great. I wish it had proven a bit more robust.

Rated 4 out of 5 by from Tinkerer's pen The pen looks quite good, and the piston system is certainly better than the converters I've used in more expensive pens. For a piston it's still on the low end, but it's perfectly functional. Appearance wise the pen looks good. The green is fairly uniform with just a touch of swirl. Mine arrived with a bad mating of the feed and nib causing it to lose prime with more than the slightest pressure. I bought the pen with the intention of playing with the feed and also with the intention of trying one of the Goulet nibs. Since the feed needed to be heat set just to work I went ahead and did it with the Goulet nib pretty much out of the box. Sadly that means I never really played with the flex nib, but if I'm ever in the mood I can heat set the feed back to that one since it's ebonite. It's now running great with a Goulet broad.

Rated 5 out of 5 by from Fun to draw or write with—learning curve is worth it I'd already purchased another Konrad (elsewhere) a while ago, and had already worked through the fiddling, field-stripping, etc. that goes into using these pens, so when I got this as a gift, I knew what to expect. If anything, this pen behaves better than my other one: posts easier, piston turns more smoothly, doesn't dry out as fast. I love the size and (light) weight of it, just about perfect for my relatively large, skinny hand. I've used this with Noodler's art nibs as well as the standard flex, the Noodler's non-flex, and a Goulet stub nib. Yes, the pen takes some getting acquainted, but it's not high-maintenance once you know its main points. It holds a good amount of ink, draws and writes well, and it won't wear your hand out. I'll probably get another one of these before long.

Rated 4 out of 5 by from Nice pen I love color on this pen, it is such a nice green. The pen itself is definitely different than handling the Ahab (of which I have 3). This uses a twist piston (I prefer the plunger of the Ahab), but it has an ink window to see when you are low. I also like that any nib can be inserted (I am using the Goulet EF). I am finding it to be too wet a writer (and drippy), despite my attempts to heat set it (maybe it's the CA heat). Other than that, it is a sturdy pen, and I am happy with it.

Rated 4 out of 5 by from Decent pen This Konrad has excellent ink flow and exhibits no signs of skipping. The nib is a bit scratchy, while some others have been just fine. Some inconsistency noted between pens.

Rated 4 out of 5 by from Defective nib The noodler nib attached was defective with inconsistent inkflow. Did not manage to remedy this problem despite flushing/cleaning the pen and tinkering quite a bit whit the nib/feeder section. Afte replacing the noodler nib with the goulet nib, the flow issue was resolved and the pen now draws wet & sexy lines:)

Rated 4 out of 5 by from Needs a little work at first After pulling the nib and feed, washing with a solution of ten percent ammonia to 90% distilled water, and a drop of dish detergent, using a toothbrush, then heat setting the nib and feed the way the goulet video shows, and finally used micromesh to polish the nib--then the pen worked perfectly. Have learned from the past to do this with every Noodler's pen.

Rated 4 out of 5 by from A great starter! I bought this a few weeks ago. The shipping was prompt (I live in Korea, and it came in a less than 2 weeks). The customer service was amazing! Packaging was a pleasure. The pen: Out of the box, I rinsed it, inked it up and had some issues with excessive flow/random leakage, but it fixed itself. I didn't have to heat set it. I'm writing with Noodler's Army General? ink, and flow is great. The line is probably medium, unflexed, and similar to my finest pilot parallel flexed (1.5mm?) it's a pleasure to use, and fun to learn flex. Great price, that you can give fountain pens a try without breaking the bank. Better performance than my 30$ cross pen and 45$ pierre cardin. Flexing does burn through the ink in a hurry, but the piston fill is easy. It can feel a little stiff or jerky when filling, but have had no issue there. It is easy to disassemble and maintain. The writing is smooth, no scratchyness noted. It is a little wet for glossy paper, but I have heard that can be adjusted yourself. It writes medium properly, and finer upsidedown. I have one issue, when I post the cap, it leaks ink out of the clip, onto my hand. Any advice? Overall, I'm very pleased, and would happily recommend this pen to any tinker who won't mind the possibility of playing with it to work. That being said, mine was fine out of the box. I want to get all the Noodler's pens!
