## Overview

The Noodler's Ink Piston Fill Flex Nib Clear Demonstrator Medium Point Fountain Pen combines a reliable 2.5ml piston filling system with a versatile flex nib capable of strokes from hairline to 1.5mm. Its transparent vegetal resin body offers durability and a unique aesthetic, while the pen’s lightweight, compact design suits professionals seeking expressive writing tools. Ideal as a second or third pen for those who appreciate customization and a tactile writing experience, it requires some nib and feed adjustment but rewards with dynamic line variation and eco-friendly materials.

## 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: 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.
Review: No. - If I could give it 0 stars, I would. First of all, the pen literally stinks. The resin that it is made out of smells like old vomit. Second, it doesn't write. At all. I wish I never spent my money on this. Save your money and get something better. This isn't it.

**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).

### ⭐⭐⭐⭐⭐ Great writing nib - Easy to Use!
*by M***B on May 30, 2018*

Back in November 2017 I was a rank amateur with respect to fountain pens and "accidentally" lucked into buying this Noodler's Ink Nib Creaper, although that's not what the description said, that's exactly what this is. I now have 7 fountain pens and I use several every day for writing in my journal, doing genealogy research, or drawing pen and ink. I have 5 or 6 bottles of ink and my favorite combination is definitely this Nib Creaper with either Noodler's Eel black or Noodler's Navy. The eel lubricates so I don't get the scratchiness of some of the fine nibs, but the Navy is such a beautiful ink. As a novice I struggled a little but quickly figured out how to work the piston fill to fill it with ink. I have cleaned it once since Nov, but normally it just works with using a soft paper towel to wipe the nib. Great being able to write a finer line and a bit broader just by bearing down. I'm ordering another one to use with Ghost Blue Invisible Ink. Overall this is an amazing writing instrument. Just never, ever fall asleep writing in a journal in bed with a fountain pen! And if you do . . . Dawn and lots of cool water and a rag can usually get that ink out.
