Awesome awesome awesome! I bought these because of the fine tip, and was concerned about spending a lot of money on refills (reviews have said that the ink runs out really fast). It does run out, but I have gotten through an entire semester on two ink cartridges (and I take a LOT of notes). This is my go-to pen.

I thought that this 0.28 tip was a little bit scratchy. I ordered both the 0.28 and 0.38, and I have to say that I like the 0.38 better.

The ink flow is very consistent and the pen tip is just like a normal pen, unlike the slicci which has a fairly sturdy tip and the hi tec c which has a unconventional tip that looks nice and doesn't break unless you write extremely hard.

I would say that this is a good pen for people who want to write small, and is definitely better than the hi tec c 0.25 tip, which is tedious to write with.

Either way, I probably won't buy this again, due to the scratchiness, but it IS a nice pen and is recommended for people who like very thin lines and dont mind the slight scratchiness as much.

Amazing, surprisingly smooth and comfortable to write with. Will definitely repurchase more and different colors.

Haven't had any trouble with it at all!

I liked it a lot until I got desperate one day and tried to use it to write on the back of my hand. The oil from my skin worked some evil magic and I haven't been able to get it to write again since. A sad waste of a good nib, but at least I can use the ink to refill my .38 Signo.

Most excellent.

I needed a pen with which I can take notes in my Bible. As Bible uses onion pages, they're very thin, and the text very small and narrow, so I needed something needlelike to take notes, but that also wouldn't bleed.

This pen fits perfectly. I'm able to take all the notes I want, and it isn't scratch on onion pages as, say, a 0.18 is.

The Uni-ball Signo 0.28mm pens have become my go-to note taking and form-filing pen. I love the super fine point, the great smoothness of the ink, and the feel of the pen. I have been using these pens for college courses, where I have to take complex notes in math and science. I have a selection of different colors in this pen line, but I use the black as my basic pen with the other colors for accentuating specific points or diagrams.

I found that I prefer these pens to the Pilot Hi-Tec-C and Pentel Slicci lines. The point has a much more sturdy feel while remaining very fine, accurate, and smooth.

I bought one of the Uni-ball Signo UM-151 .28 tip pens whilst visiting in Japan last year, but didn't try it until I returned to England. It was brilliant - fine smooth consistant line enabling me to get lots on a page when making notes. When the ink ran out I found I just couldn't get the same pen in Britain and hunted on the internet until, I found Jetpens.

I ordered both .28 + .38 tip pens and also refils - a little apprehensively as they were to come from the USA. My order and dispatch were both acknowleged by email and the items arrived safely within 10 days. They are absolutely identical to the one I bought in Japan. I'm highly delighted.

I bought the .28 and .18 black versions of this pen on the recommendation of the Penaddict. I love this pen (.28). And in my preliminary tests I prefer it over the .25 Hi-tec-c. Has a nice feelin grip. Writes in a nice smooth manner. I have not noticed any issues with ink flow. And the small cap is unlike anything you will find in the States. It snaps nice and tight into place. Buy a bunch of these you won't be disappointed. For those considering the .18 it's almost like a different pen, that extra fine nib does seem to have some flow issues and feels a bit scratchy.

I love this pen! It writes quickly and smoothly, making clear, crisp lines.
It's comfortable to hold even for extended periods of time. I do find that the ink runs out relatively quickly if you're writing a lot, but refills are inexpensive so it's not much of a problem. The pen feels very sturdy but thin.

WOW. I think I have a new favorite pen. And it happens to be purple.
-This pen puts down a Tight. Clean. Sharp. Line. I have just tried out Slicci's and Hi Tec C's, and the Signo is outperforming them.
-Even more impressive, it writes very smoothly for a pen with this fine a point. Definitely not scratchy. It blows the Sarasa, Hi Tec C, and Slicci out of the water, in this regard.
-Despite being smooth, it's still easy to control. My handwriting looks amazing.
-The pen starts writing great after the first word or so. After that, I only notice it going out a few times (usually at the top of my e's). Barely noticeable.
-It has a wider barrel than most of its fine point competition, which makes it more comfortable. The grip is nice, but still a little hard.
-The Signo looks like it has a lot more ink than its competitors. I've written a lot with it, and the ink level has barely moved. Compare that to my .3 Slicci ink level, which plunges after every writing session.

I could see this pen being too fine for some, but not for me. And definitely a pen for good paper, like Clairefontaine 90g. I'm going to be buying a lot more of these.

A few notes about my writing style:
I write quickly with a light touch and my normal print fits nicely on college ruled paper. I’m a righty and my handwriting is mediocre at best, so I tend to choose finer point gel/ball point pens to help with legibility. I don’t use liquid pens because they tend to spew ink when I twirl them while I’m thinking.

I liked the Signo 0.28 very much for its fine point and comfortable form factor. It is a bit scratchy at first but as you break it in, that feeling goes away and it writes a quite smoothly for an ultra-fine. The quality of the pen itself is superb but the grip starts a bit higher up than I would like, hence the 4 star rating. The cap fits snugly on both ends and the pocket clip doesn’t break even with moderate abuse. I got about 40 pages of dense writing out of one pen which is pretty much average for an ultra-fine gel.

Fantastic pen for artists everywhere. I highly recommend both this and the Zebra Sarasa (0.3mm).

I can't describe how much I like this pen. I have very small writing (a friends once described it "like a mouse writing with a pushpin dipped in ink") and this pen allows me to have clearly defined, legible, letters with no smudging. The lines are thin and crisp without the pen feeling scratchy - a problem I've had with other micro-tip pens like the Sarasa.

It sits well in my hand, which pushes it over the Slicci in my opinion. Compared to the Signo, the Slicci feels too small and slightly cheap.

I've only had a few issues with this pen. Once the nib was bent at the tip, making it unusable. This is my fault for rough handling. It probably bent when I dropped it, or if I put it in a bag without recapping it. Secondly, one of my older pens doesn't lay down as clear a line as it used to. It still writes, but the letters look faded, like it isn't depositing enough ink.

Still, gorgeous pen, I highly recommend it in any colour.

I love this pen. I have several in this size and refills to keep me going. I use it in art journaling quite often. It doesn't write over acrylic paint very well but if your using paper it works great. You can write in a lot since you can get such small lettering with it. I write very large normally but with this pen I seem to write smaller. It's a nice change. Would recommend to anyone who likes a fine line.

I just found the perfect pen for notetaking and charting (Nursing School)
After my love affair with the Signo Bit 0.28, decided to give these a try and I am now wondering "what took me so long to order these". I love the inkflow and balance. just wish the cap was a little longer for asthetic reasons. All in all this is the perfect pen for my needs. I am on my way to a box of ten right now!

I just bought eleven different kinds of pens and this is my favorite of the bunch. I scarcely have to use any pressure to produce a consistent fine line. Comfy to hold. My one concern is that when I store the cap on the back of the pen it seems a little loose there.

I have used .25 Hi-Tec-C's and .25 Pentel Slicci's. They're both wonderful gel pens, but I think the Signo DX UM-151 is superior to both.

Although the Signo is not as slick as the Slicci, it has a thinner more consistent line. The pen feels like a Hi-Tec-C but the tip of the pen does not stick or catch on the surface paper like the Hi-Tec-C. The weight of the pen is wonderful and does not feel too thin like the Slicci's and Hi-Tec-C's sometimes do.

Favorite pen of all time. Sturdy tip. Always smooth. I do wish they made a retractable tip, and that I didn't mow through them so fast. Near perfect.

The Uni-ball Signo DX UM-151 (028) has become my new favorite pen. I tend to write small, with at least two lines of text for every traditional college ruled line. I previously used normal 0.5mm pens, however the paper we started using at the office apparently allows ink to bleed more than normal, and made my writing difficult to read. I bought an assortment of pens from 0.18 to 0.5 mm and tried them all out, with the Signo DX being the clear winner. The lines are smooth and don't bleed at all on the page.

Best pen i've ever come across
0.28 tip looks very clean, i'm sure it also holds true for the bigger tip
Ink is striking to see

Note: put the cap on the other end when writing. Provides just enough weight so you don't have to exert any pressure on the paper. You can experiment on that

I love these pens so much that I had colected all the colours! When I write it was so smooth. My classmates also colect these pens! Fun! Hope to see new colors coming out for sale soon... :)

yowza! this pen is the best! ive fallen inlove with the .28mm! ive always been a fan of uni-ball signo pens they carry in the US. but now im hooked on the .28mm thickness. its the smoothest write youll ever have! no joke. the .38 is also fantastic, but i like the .28 the best. im addicted!! (id trade my hi-tec-c 's for this)

I first heard about the 0.18 mm pen, was rather curious, and then decided that the 0.28 mm pen might be a more practical one for daily use. I purchased many of these pens (and of different colors), and they are absolutely amazing. I've always been sort of against gel pens from experiences with very ordinary ones in the U.S. that don't have consistent ink flow and make a line too thick. I've used this pen for many months now, and I absolutely LOVE to write with it. A gel pen made right! Waterproof too! Thin, readable line, consistent ink-flow. I do have to warn you that if you drop this pen on the tip, it -will- render it non-usable (but you should expect that considering the tip is so thin!). As long as that doesn't happen, this pen will last you a good while, and I recommend this to anyone who loves to write small and write a lot! Very smooth! I even ordered these as gifts for others!

I like these pens. The ink is nice and black and goes onto the paper evenly. The have a nice tapering nib that makes for a strong tip. They have a rubber grip that is not to soft and feels good in my hand. The cap is short and when on the back of the pen does not rest in the web of my hand. The pens have good balance allowing for long writing periods.

The 0.28mm nib drags the worst of the 2 sizes but leaves the thinner line. The 0.38mm nib writes the smoothest but produces a darker line. The 0.38mm nib is perhaps the better of the two as an every day pen. It writes as smooth as any other uni-ball 0.38mm gel pen.

The best pen I have ever written with.
The ink is smooth, and flows extremely well for a .28.
The tip feels extremely sturdy, so I don't worry about pushing too hard or anything.
The barrel feels strong, and the grip is really nice as well.
It's very comfortable to hold in one's hand.
Overall, I can't wait to get some more of these! They will be my pen of choice for a long long time.
