Nemosine Singularity Fountain Pens


Nemosine Pens may be a new name to you, but it has been around for a few years. Unlike its competitors, the company has staked out the under 1.1 mm italic nib as a unique part of its offering. For as little as $14.99, is it a bargain or a waste of pocket change?

The box states

  • precision nib made in GERMANY
  • pen body made in TAIWAN
  • inspected and packaged in USA

So the pens are of mixed heritage. The box also announces a “3 YEAR PERFECTION WARRANTY.” Apparently they really like putting info in ALL CAPS including the company name, NEMOSINE. The packaging amounts to a simple white, cardboard box that contains the pen, instruction sheet, and some cartridges to get things started. Given the price point, this is an economical presentation that suits the product.

The two Singularity pens I purchased arrived in perfect condition. The company has misnamed the magenta since it is most certainly purple. The aqua is more accurately named and a very attractive color at that. Both have silver-colored furnishings and stainless nibs. Neither has any obvious flaws though they haven’t been in rotation long enough to know whether they will endure the test of time.

The size is very comfortable for me and the design is quite pleasing in the transparent, demonstrator style. There are other colors available. The Singularity feels sturdy, but lightweight. The cap screws on solidly which makes this model a likely prospect for a carry pen. In addition to the visual treat of seeing the inner workings, the level of ink is always on display. This feature makes a demo a very easy travel mate. Grab and go, you know?

Sometimes small things can make a big difference. The convenient piston converter contains a tiny plastic ball that breaks the surface tension and keeps the ink flowing into the feed. This is a plus and something all converters ought to include.

If you really want to load it to the max, this model can be converted to an eyedropper-filler with a smear of silicone grease. Get the sort used on fountain pens for best results.

Isn’t that an attractive nib? It really elevates the pen’s appearance over anything else in its class.

The Singularity comes in extra-fine, fine, medium, broad, 0.6 and 0.8 calligraphy tips. The 0.6mm nib is quite sharp making it an italic. It does not glide, but it can add character to letter forms. A lubricating ink will improve its performance. The sweet spot is on the small side, but in line with the nib size. This could make the 0.6 a challenge for someone who rotates a pen. It isn’t an insurmountable problem, but something to consider. However, the nib size is very well suited to grid paper and performed admirably with Noodler’s Purple Martin in a Midori #002 Traveler’s Notebook.

The 0.8mm is smoother and is not quite as sharp so it is closer to a stub. The sweet spot is larger, but so is the line. It’s an all-purpose size for me, but then I do like wide nibs. For someone who wants to explore stubs, especially with little investment, this is a good entry pen.

The two pens are twins in one regard. They are chatty with the 0.6 out-squeaking its sibling. Paper and ink can influence this trait so an ink that aids flow will reduce the chatter at least on a very smooth paper. I used to live with a Society Finch who thought a squeaky, chattering fountain pen was signalling an invasion. He would harass the offender until it went silent. I am not so sensitive and find the sounds to be inoffensive.

The weakest aspect of both pens is the flow, but I have found that to be true with other entry-level italics including the Lamy and the TWSBI Eco 1.1mm nibs. The Singularity flow is sufficient to keep up with the nib’s width and rate at which it puts down ink and neither pen has failed to write. However, at times the line isn’t as filled in as it should be or the outlines as consistent as one might like. Writing at the right pace for the flow will achieve best results.

For a brand comparison, the Nemosine nibs are more narrow and have more consistent flow than the Lamy 1.1mm. The Lamy broad nib is smoother and wetter than the Nemosine, but it isn’t crisp like an italic. Lamy pen has a unique style while the Singularity has a more traditional design.

For another comparison, I like the look of the Singularity better than the TWSBI Eco and the 0.8 stub is at least as good if not better than the Eco 1.1. Flow is more inconsistent with the Eco than the 0.8 stub, but ink can play a significant part and some brands and colors will be more helpful than others. Paper is a factor, too, and slightly absorbent paper pulled just enough ink from the Singularity nib to produce relatively clear, clean lines. Isn’t that a neat trick!

At the price point, there isn’t much to lose. However, I was pleasantly surprised at the Singularity and will get plenty of use from these low-end gems. As proof, the aqua demo with Diamine Marine earned its second fill in only a matter of days. From the standpoint of eye-appeal, it’s a happy-looking pen and is sure to follow me everywhere. Next thing you know, it will be begging for a matching journal and myriad accessories. My inexpensive pen could become a rather expensive hobby. At least I will have an abundance of color to show for it and that is always good for an inkophile.

xFountainPens offers the lowest prices I could find on the Nemosine Singularity and carries replacement nibs as well.


  1. The .6 nib in a clear demonstrator with Iroshizku Ina Ho has been a joy for annotations in books and notes in Midori notebooks. I did find the nib needed a good flushing after 2 fills. No chatter at all.

    I think I will try a more lubricated ink soon.

    On the whole, an excellent pen for everyday use.


    • It’s a good pen to carry with no worries. Even in the hands of an inquisitive novice, it works well enough and if someone is too rough with it, the Singularity can easily be replaced.

      I only have a sample of Ina Ho and have been keeping it for special use. It might be just the ink for one of my clear Platinum Century pens or the TWSBI Diamond 580. Definitely something to look forward to and a good reason to clean pens that aren’t getting much use. No doubt the right ink would make them more appealing to use.

  3. If you are a beginner or a student maybe this is a good pen to start with. Im so glad that affordable pens are looking so good and writing so well!


    • Jud, you are right about the Singularity. Mine came with six cartridges which is an ample supply to get familiar with using a fountain pen.

  4. My sister has a Nemosine Singularity Medium Nib and I would say your review is quite similar to my own feelings. She had a problem with leaking when she used the cartridge, but when I switched to the converter, I didn’t have any problems.


    • Interesting that the nib size doesn’t seem to impact the flow and the quality is consistent. I wonder if it would make a good gift pen especially with the holidays not so far off.

  6. I absolutely love my Nemosine pen! I use a convertor and Noodler’s Ink in Cactus Fruit. It’s pretty much one of my go-to pens and often in my rotation! Great write up!

  8. I love my pen. However I don’t know which refill cartridge fits my Nemosine pen. There doesn’t seem to be a cross reference chart for this pen. Can anybody help me find which cartridge I’m to use.


    • The Singularity uses standard international cartridges, long or short.
