First Fountain Pen & it's so good I'm going to stop looking!
I love this pen! This is my first fountain pen and in all honesty I don't think I'll get a different one, this has been the smoothest and most consistent writing experience I've ever had with any pen. It's $20 so amazing value, it has a high quality German steel nib so it glides across the page like a finger over fine silk and the ink delivery is reliably consistent so there's no skipping. The Pen's design is simple but clearly thought out with how the cap when it's posted seemlessly extends the barrel making it long enough for my large hands to use comfortably. It's light but still heavier than a typical rollerball or gel pen, just enough so that is writes under its own weight. I am incredibly happy with this pen as my first so much so that I don't think I'll keep looking for something better. This would be great gift for someone you know that just can't seem to find that right pen for them. This uses a standard international Schmidt converter for using bottle ink (cheaper than cartridges) and it does not come with the pen only a single Schmidt black cartridge. I recommend HongDian ink bottles as it flows consistently and dryes quickly. Hope it helps!

Needs lots of breaking in - but worth every penny
FINAL update. What a rollercoaster. After weeks of breaking in this is now my go to pen for drawing. Read all that ⬇️ But now- with the same inks and paper-this pen writes and draws beautifully. Couldn’t ask or want for anything better. Yet another update and downgrade: This is the most inconsistent pen I’ve ever used. No matter what ink or paper- sometimes it writes like a dream -other times it’s a nightmare. No rhyme or reason. I want a return or a replacement. I’ve heard so many good things abt this pen im hoping mine is just defective. Update: maybe this pen needed a little breaking in but now it writes beautifully. I use it mostly for drawing and in a strange but nice way it feels like drawing with a pencil. Thats not a bad thing- but if you want a pen that “flows” and lays down a line effortlessly this this pen doesn’t really do that. (Not with the ink cartridge that came with the pen in any case) First review: Amazon said “expected delivery” Dec 16-31. But it arrived on Dec 8th . Pleasant surprise is an understatement! BUT, I hate to say it’s finicky. At first it wrote like a dream and I was planning on buying another one. But (evn using the ink cartridge supplied by the manufacturer) after about an hour it started skipping and needing a lot of pressure to write. I’ve been cleaning the nib, shaking the pen etc , but it’s just so inconsistent. I want to love it - and I DO when it occasionally does do its thing it’s my dream pen- but I can’t understand why it’s so random. (I’ve used the same ink and paper for hours now and I never know how it’ll perform)

Great ink flow
Pen is an affordable and great starter fountain pen. Ink flow is great and NIB doesn’t bleed. You will need to order additional cartridges as it comes with 1. The pen is extremely light, but becomes too heavy with the top attached. Overall, great pen at great value so far.

Writes very nicely and is my EDC fountain pen despite its few flaws
The most important thing I can say about this pen is that it writes very smoothly, very enjoyably. My EDC pens before this were both Pilots, a Metropolitan MR and the Kakuno and this from an ink application point is the nicest of the three. The nib is what I would consider fine, but is thicker than my fine point Pilots; I fine it to have less bite into paper than both of those but still a lovely sound on the paper. For reference I have used both the ink that came with it, Pilot Namiki black and Pilot Iroshizuku Ajisai and all three performed well with it. As far as ink delivery and nib behavior, this pen is very nice. As for its flaws, I find most to be in the form factor/ body design. I appreciate the appearance and lack of heft, as well as the rigidity of the metal body. It is easy to put in a shirt pocket or pants pocket and forget it is there. However, I find its small diameter/constant diameter to be a source of discomfort in writing. I have smallish hands and this pen is still a bit thin for my preference. I wish it was maybe 20-30% thicker. This means that despite the pleasure of writing with it, if I need to write for long periods I still use my Kakuno or Metropolitan. I also am not a huge fan of how the cap engages either in capping or posting. While it is clean from a design perspective you have to be more intentional in capping/posting it; it cannot really be done as quickly as pens whose caps simply slide over the end or tip. This doesn’t sound like much of a big deal but if you are frequently doing this (as I write in a lot of little bursts at work jotting down notes) then you might notice it like I have. Again, this is nitpicking quite a bit TBH but I did notice it as a point of consideration for using it. I also found the ink capacity of be a bit in the small side; I haven’t measured it precisely but it feels to be around 50-60% of the volume of my other pens so be prepared to fill it more frequently if this is the only pen you use. Overall, I think the experience of actually using this pen to put ink on paper outweighs its design choices that I would change. I have used this pen everyday since I got it and I don’t foresee that changing. For the $$ I would definitely recommend someone add this pen to their list of EDC pens!

Excellent "everyday carry" pen
This Muji fountain pen is a great everyday carry (EDC) pen as it's a great price for a quality pen that does everything a pen should do and look great while doing it. The knurled grip provides the right amount of grip without being aggressive. The snap function of the cap is secure and satisfying. The caps posts as well, but I do not post my pens so it's not that big of a feature for me personally, but it's good to have a nice aesthetic when posting is desired. The nib is a western fine line, which is good for work or play. The included ink dries quickly and is a standard deep black, but it accepts international standard cartridges so one has a large selection of inks to choose from. Cleaning is easy, just remove the cartridge then run the nib under water until the water is clear, allow to dry for a few hours, and it's ready to go for another round. I highly recommend this pen for someone who's looking for an EDC or wishing to break into fountain pens. There are other options in this price range for starter or EDC pens, but for the money you will be getting a great-looking, slim aluminum fountain pen with a solid nib that has been reliable (with my unit, at least).

Awesome fountain pen for sketching and writing.
Awesome everyday fountain pen for sketching and writing. No flex in the nib, don't try to either, but it's not for calligraphy. It's just a solid, minimalist design that has so far not given me any flow issues. A "wet noodle" of fine tipped nibs and takes other inks well. For about the same price as a Pilot Metro though, the Metropolitan is the better pen. For that matter though, a jinhao fountain pen also looks good, writes well, and only costs like $6, plus has a little flex to the nib for a little bit of what's probably a surprising, welcome spencerian script flair to add to your writing. This is more a workhorse pen you wouldn't feel too bad about losing or breaking for the price point, but being made all aluminum- breaking it (unless it's the nib tines or threading maybe) might be a hard task. I do think $15 and up is still kind of priced too high. I'd own a ton of them if they cost the same as my beloved parallel pens. Muji's do start up their ink flow pretty reliably each time though. Even after being capped for a long time and using different ink types. I've had Noodler's Apache Sunset, Pelican's Black, Diamine Oxblood, and even Maribu Aqua ink in them with no issue so far. It gunked up a bit here and there using Jacques Herbin's Emerald of Chivor, but kinda expected that with all the shimmer, and it still put out ink more reliably than a lot of pointed dip pens would with the Chivor. They're really best to me for sketching, filled with some good old Noodlers Heart of Darkness.

Narrow barrel, but still pretty comfortable to write with.
The Muji aluminum fountain pen is fairly comfortable in the hand. It is lightweight due to the aluminum construction. This pen is designed to be posted. I’m not really a poster of my caps. I will usually hold the cap in my free hand when writing unless the cap posts deeply and securely. However, the design of the Muji aluminum fountain pen seems to make the writing experience better when the cap is posted. I tend to hold my pens at the very bottom of the section, close to the back end of the nib. Holding the Muji aluminum pen this way is uncomfortable because of the rather sharp step down between the section and where the cap slides into it. When I post the cap, technically making the barrel longer (due to the virtually seamless design of the cap and barrel) I grip the gnarled section a bit higher up, thereby avoiding the sharp step down completely. I really like the functional design of this pen. What I don’t like so much, is the fact that a convertor is not included. However, an ink cartridge is (an international short). Because of the design of the Muji aluminum fountain pen, there are a few crevices that would have to be cleaned every time the pen was filled from a bottle of ink. Or to avoid the messiness, a blunt tipped syringe could be used to fill the converter with ink as needed. Of course, the use of ink cartridges, avoids all the messiness and helps to keep the Muji aluminum fountain pen, looking pristine. I am currently using a Waterman long ink cartridge, which is working quite well and has much more in capacity than an international short. When I use the ink in this cartridge, I will refill it with bottled ink. This is the only cartridge/converter pen I own that I will probably use cartridges only. Bottom line, these are pretty nice pens. UPDATE: The bottom finial collapsed. This disabled the ability to post the cap. I’m not usually a cap poster however, I must admit the design of the Muji aluminum fountain pen really does allow the posted cap to enhance the writing experience. I was able to pop the finial back into place, but in a weekend state. Once I try to post the cap again, the same problem occurs, and I have to pop the finial back in place again. Therefore, I don’t post this pen, like many other fountain pens I own. Unfortunate, because this one is meant to be posted. Hence minus another star. I have pens that cost half of what I paid for this one and I have not encountered any problems with them whatsoever.

Oh how I love this fountain pen - excellent for drawing
I first tried one of these fountain pens a few years ago. I love how, even though being a fine point, the ink just flows without skipping. It is an excellent pen for inking drawings, and it's never given me any troubles. Until I lost, misplaced, or had it stolen. When I couldn't find my pen, I decided to buy another one, which I did and I was VERY happy that it's quality, look and feel and writing experience remain the same. I like how thin this pen is and how the cap slips onto the back of the pen while in use. It's a flat aluminum colored pen and it comes with cartridges filled with black ink. They look to be international standard type so I imagine you could get any color ink refills you'd like, I usually just use black in mine. This is a good beginner's fountain pen because of how easy it is to use, it just works without issue -- there is no "breaking in" or adjusting the nib, of the several I have purchased and used over the years, none have given me issues or need to be adjusted. Writing is comfortable and not a strain, much like writing with a regular pen or pencil. I likely will buy it again.

One of the most underrated pen
I am writing this review after using it for 2 months. I came across this via youtube video while searching for metal fountain pens, before that I never heard of it. And after using it, I must say its a great product. Unusually small cap as compared to other fountain pens, takes sometime to adapt to it. Some of the key features are very smooth wet nib, nice sleek grip, full metal body. Totally loved it and now it has replaced my Lamy Safari in daily usage. I tried sketching with this pen also and it worked amazingly. Must have, long lasting pen.

Overall, a fantastic purchase for those seeking a stylish, high-quality fountain pen without breaking the bank.

Una piccola penna che scrive benissimo
Lo stile è anonimo, da prodotto industriale, il materiale è semplice alluminio, il prezzo è modesto ma ...scrive benissimo, con assoluta regolarità (niente salti o false partenze). Il suo tratto, ufficialmente "fine" , è in realtà abbastanza generoso, merito di una inchiostrazione più che adeguata fornita da un ottimo alimentatore. La traccia si dipana quasi priva di feedback: è un vero piacere! Il pennino è anche dotato di una inaspettata elasticità: aumentando un poco la pressione si riesce ad ottenere una larghezza quasi tripla. Per l'alimentazione ho lasciato da parte la cartuccia in dotazione ed ho optato per un converter, preso in prestito da una mia vecchia penna. A questo proposito sarà utile tener presente che questa penna non accetta i cosiddetti converter (o cartucce) standard. Con un buon inchiostro (da scegliere in un repertorio quasi senza limiti) questa penna sarà in grado di fornire prestazioni di assoluto rilievo: a questo prezzo non si può davvero chiedere di più!
