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 my best pens
I have a collection of 20+ fountain pens ranging from $11 to $350 each. This is in the top three quality-wise, and bottom three price-wise (so inexpensive for what it is!). It’s very smooth, it behaves very well on many types of paper, the grip is fantastic (not slippery or stepped like a Pilot Metro), writes very consistently with stock ink (although my favorite ink is Platinum Carbon Black, which you can refill the cartridge with using a syringe), does not leak and is easy to clean if it does, is very giftable, etc. I have had 10+ friends and family members test out all my pens on FP-friendly paper, and this pen almost always falls into their top three as well. I recommend getting a refillable piston-style cartridge for it and a bottle of your favorite ink to prevent wasting the plastic cartridges (and the money needed to keep buying them). Hot tip: Muji’s notebooks are also FP friendly, specifically the tan 184-page “POCKETNOTE” book with the red ribbon (pictured). There is no bleed and very little ghosting even with black ink. Do yourself a favor and get this pen if you are just getting into fountain pens — you will not regret it, and will likely keep coming back to it even as your collection grows :)

The Cool Muji Aluminum Pen
The first thing I noticed when preparing to write with the Muji pen is its lightness. At 20 grams it not light for a pen, but lighter than I expected for a metal pen. Then I noticed its clean, simple design. When prepareing to write you can’t help but notice the unique way it posts: the last 4 mm of the cap actually slide into an all but invisible groove in the end of the barrel. The nib is not particularly wet although you couldn’t call it dry. The Muji writes smoothly but does have a bit of what I call “phantom drag”. That happens when the iridium part of the nib is very smooth but the tines are stiff. It’s like writing with the nail with a smooth point. If you write with any pressure the nail moves smoothly but meets resistance because the paper is being pressed down in order for the tip to move forward. Because the resistance is quiet and smooth I call it phantom drag. A more flexible nib would simply bend up to avoid pushing the paper down. I admit that I write with a heavier hand than most – too heavy really. If you write with a light hand you may not notice any drag. I will that say there was minimal flex when I tried the figure 8 test for line variation. I was able to coax out some variation, but not much. Having said all that, I’ve got to add that the pen is really cool. It looks cool (reference MOMA design recognition) and feels cool in the hand. And I love the way the cap posts. Because it clips easily into the pocket, is inexpensive and is stiff enough to make carbon copies, it is a good pen to carry with me most days. For longer writing sessions though I like a pen with a little more size, heft and flex.

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)

I own many fountain pens (possibly too many) and this is one of my favourites. It's compact, comfortable, very light, and stylish. It also has one of the smoothest nibs I own which makes it a pleasure to write and sketch with. In fact it has a smoother nib than other pens in my collection that cost ten times as much making it fantastic value. I've no idea if I was lucky to get such a smooth nib with my first Muji fountain pen but I've read other positive accounts so perhaps it's a sign of great quality control. The only minor negative point I can think of is that it comes with only a small international cartridge but this means it can be used with a large international cartridge or convertor so it's easily remedied. Some people classify this as a starter pen and while I think it's true that its low cost and ease of use put it in the same league as the Lamy Safari and Pilot Metropolitan and it's not as fancy as high-priced pens it's definitely a pleasure to use at any time. Highly recommended.

Der Füllfederhalter ist aus Aluminium im Industriedesign gehalten. Er liegt wunderbar in der Hand, ist ausgewogen und lässt sich dank des rauhen Griffeldes ohne Kraft sicher und locker halten. Die Kappe schließt passgenau und der Clip macht eine stabilen Eindruck. Nach dem Einfügen der Tintenpatrone konnte ich sofort loslegen. Kein Anfeuchten der Feder, kein Eindruck Ken der Patrone. Die Tintenabgabe zur Feder ist flüssig und reißt auch beim schnellen Schreiben oder Zeichnen nicht ab. Die Feder in der Strichstärke fein (F) entspricht dem europäischen Standard. Das Schreibgefühl ist phantastisch. Die Spitze ist grandios, gleitet hervorragend in alle Richtungen, ohne kratzen. Ich kann den Füllfederhalter uneingeschränkt zum Zeichnen und Schreiben empfehlen.
