## Overview

The Noodler's Ink Piston Fill Flex Nib Clear Demonstrator Medium Point Fountain Pen combines a piston-filling mechanism with a transparent body and a versatile flex nib. Designed for adults, it offers a lightweight, ambidextrous writing experience that transitions smoothly from fine to bold lines, making it an affordable yet expressive tool for professionals and fountain pen enthusiasts alike.

## Description

The scarce but popular Noodler's flex nib fountain pens enter a new design available in several new marbled colors. Each pen is uses a piston-filling mechanism which accepts bottled ink only (may we suggest Noodler's Ink?) and is fitted with a special auto-vent flex nib that can go from a hairline to 1.5mm stroke on paper using slight hand pressure to spread the tines of the nib. Definitely a great value considering the low cost to own a flex nib fountain pen.

Review: I’m very pleased with this pen and decided to keep it - I’m a little dissapointed since I was under the impression that I ordered the Ahab but instead I received the nib creaper. Luckily, I’m very pleased with this pen and decided to keep it. The pen certainly has an odor that many are attributing to the fact that the plastic is manufactured using vegetable oil but it’s not offensive to me. I love that there is no need to purchase a seperate converter. Ink it and it’s ready to go write out of the box.
Review: Not a first pen, but definitely a second or third. - I do think the Konrad and the Ahab are better pens, but if you like thin and small and still want a piston filling demonstrator pen with a flexible nib, this is where the money's at. I have two, one that I ground the feed out to gush ink, and this one, which I kept stock. Noodlers pens DO REQUIRE SOME FIDDLING. DO NOT BUY THIS AS A FIRST PEN. You will have to likely adjust how deep the nib and feed are in the body (further out = more flex, closer the feed is to the tip of the nib, more inkflow) and maybe use a razor blade to cut the ebonite feed a bit, but this will take any standard #5 nib as well, and is a proper piston filler. The biodegradable vegetal resin isn't as crystal clear as a TWSBI's plastic, but it's still quite clear, and it's tougher than any other plastic you can think of. Nathan Tardiff of Noodlers has a video of himself driving over a konrad (Same material) with his car twice and it wrote fine, and then firing one out of a shotgun (it survived) It does have a VERY strong odor out of the box, some people HATE the smell, so if you don't like the pen's odor, stick it in a drawer for a week and it will dissipate quickly. It's a very thin, light pen with a good posting cap. The nib is nice, will flex very broad (western EF to about a 1.1-1.5 stub) though it does require way more pressure than a "vintage" flex pen, if you want to write bold and broad, this will do the job, no problem. It will get tiring to do after 10-15 minutes, unlike a vintage flex pen, but that isn't this pen's intent. It does write like a slightly springy gold nib when writing normally, which I really like (not like a soft nib, but softer than regular steel nibs) Piston mechanism is smooth, simple, and reliable, and it holds a good amount of ink (2.5ish ml) The only issue I have with these nib creapers is that the cap has no inner seal, so it can't be sat in a drawer, inked, like a platinum with a slip and seal cap or even a jinhao. The konrad has an inner cap and the ahab seems to not have much issue (my neponset is ebonite without an inner cap but seems to not have trouble either) it will dry out if left for a week inked and unused. So only ink this pen up when you want to use it, and the rest of the time, keep it empty, and you won't have any issues. Overall, if you have a few dollars more and don't desperately want the thinnest pen you can find, I suggest the ahab, or if you need something a little smaller, the konrad, which are a bit more versatile and have a more easily swapped #6 nib. But for what it is, this is a solid little flex pen.

A: no the nib creaper uses a  #2 the Ahab and Konrad are #6 nibs

**Q: Can I put white ink in this pen? If so what kind is best?**
A: Have you tried D'Artrementis white ink? It is made for fountain pens.

**Q: Can we see a writing sample?**
A: Better check youtube. Personally I was hoping for little more flex.

**Q: I'm a bit confused. Is this  listing for a clear demo pen or a blue lapis pen? The title and the description don't match.**
A: It's the clear demonstrator of title and photo.Description is probably just copy-pasted from a similar listing. I don't think I even read it before ordering - Amazon have been successfully deemphasizing it (at least on mobile).

### ⭐ Smells like rotten cheese 🧀, stinky feet, & worse…
*by A***A on February 27, 2026*

I’m so grossed out. In all my years of fountain-penning, I have never had an experience like this. I received a new pen order. I opened the box and the smell was so overwhelming my whole body immediately recoiled. My husband was in the kitchen when I opened the box. He was standing ACROSS THE ROOM and within seconds shouted out, “Uh!! What’s that SMELL?!!” The pen fell out of the plastic wrapper. I picked it up to put it back in. The smell stuck to my fingers!! I immediately washed my hands and the smell is still faint under the soap’s perfume. 😱🤢 My stomach is turning (no joke). I went to Amazon to check the reviews. and Eighty eight out of over six hundred people have complained about smell. 😱 One person even noted that it smelled like cheese. They are wrong. It smells like *rotten* cheese. That’s been fermenting inside a dirty sock that’s been worn for weeks, then stored under someone’s yeasty fat roll, who hasn’t taken a shower for a couple more months. Too much for a description? No. No It’s not. It’s not too much. Because that’s how bad this pen smells. 😩 One review said it smelled up their whole pen case and all of the other pens in it. Ew!! I would never put this thing in my pen case. My stomach is still turning. My question is… why would a brand new pen smell like that?! 🤢 I don’t know if I will even return the pen. I want it out of my house asap so I may just throw it away. Also, my Fountain Pen Revolution Ultra flex works way better than this one. There should be a warning in the description about the smell!! 🤢🤮🥴
