, August 29, 2011
Yes, it's a specialized pen, and I don't think it would be comfortable for
extensive writing sessions. (I'd suggest the Hi-Tec-C .25mm for that.) But I
needed something this fine for annotations and small details in my sketchbooks.
This pen has performed beautifully for three years now, on a variety of papers.
A big plus for me is that the ink is absolutely waterproof, unlike the
Hi-Tec-C's. So I can go over my drawings with watercolors without any fear of
the color running.

I bought this pen because...
, March 13, 2012
I bought this pen because I happen to write small. (Less than 1mm text height to
put this into perspective.) It definitely does its job very well as a small
writing pen. I use this for all my classes, from writing notes between lines and
writing entire essays on 6 lines of wide ruled paper.
- The thin tip enables you to write thinner, smaller, and also in between
- It also has excellent ink flow so you can write pretty fast with a pen this
- It runs out of ink rather quickly. Buy lots of refills if you want this pen to
last. In my opinion, it's a price I'm more than willing to pay to write this
- If the pen is dropped tip first, it may start to bleed out ink. Not only will
that make your line thicker than 0.18mm, it will waste ink as you write.
As a side note, if you lend these pens out to other people, tell them not to
write on their hands if they are heavy handed. (They’ll cut themselves.) Also,
some students (AP students in particular) may want to buy these pens from you.
Either redirect them to this website or buy some extra to give away or sell.

Nice pen to own. .18mm size requires a slower hand to lay down proper ink flow
but with patience is well worth the payoff. Unique +

What a pen, my friends,...
, September 7, 2012
What a pen, my friends, what a pen.... Think on this for a moment, the tip on
this pen is, quite possibly, the smallest all metal nib made. You can ink very
small, very thin lines with this, in fact, if you go too fast, you leave nothing
but an indent in the paper. What makes this pen shine for me is the fact that
you can use speed and pressure variations and whatnot to create even smaller
and thinner lines than you ever could make with a felt tipped copic that is
.05mm. It takes a fast yet gentle and painstakingly careful hand to work with
that tiny copic. This uni ball signo bit is a beautiful thing because it costs
less, much less, is very sturdy compared to the copic felt tip, and is
relatively easily replaced.
Now, that said, the ink goes quick, like a reviewer said, because uni ball is
cutting costs and putting less in. I just got it out of the package, and it was
half empty. Not only do they put less in, but the space which contains the ink
is ludicrously thin as well. The pocket clip has not broken yet, but I put zero
trust in it due to the ominous rattlings coming from it. Refills are, actually,
quite expensive, just a little less than the full pen itself.
In conclusion, I would only get this for annotation or drawing, and I would, and
will, get it again.

For the last few years...
, August 31, 2012
For the last few years these have been among my favorite pens and by far are the
best of the micro-fine points on the market today. My review of the Uni-ball
Signo Bit .18 can be be found at the link below:
Wow - just Wow. Keep...
, May 7, 2013
Wow - just Wow. Keep in mind that the "0.18" refers to eighteen one-hundredths
of a millimeter, and there are about 25.4 millimeters to an inch, and you
quickly come to the realization that calling this a "fine point pen" is an
understatement of considerable magnitude. The engineering required to make a pen
like this is noteworthy, but Uni-ball makes it even better by making a pen that
writes clean, unbroken lines of extraordinary thinness. I actually had to look
carefully to be sure ink was being deposited on paper. Want to transcribe a
textbook onto a Rhodia Bloc No. 10 notepad? Most of a concerto onto one sheet of
musical staff paper? Get a couple of these, and some refills, and you'll be
ready to go.

It is very useful to own such a extra super mega fine pen, there are many
situations when writing with a fine point is required.

This pen is not for everyone,...
, July 19, 2012
This pen is not for everyone, but I love to draw with it. I use it to lay down
my first reference lines in my pen and ink portraits. I also use it for very
light cross hatched shading. It is as think as a very thin Rapidograph. I prefer
to take this out with me sketching than the Rapidograph because if it breaks or
is stolen I'm not losing a $15 pen.
I'd like a thicker more comfortable body for this pen. The body and grip area
are very thin so I find myself reaching for thicker pens. I keep trying to jam
this into other pen bodies, eventually i'll find a thicker one that it fits
If you are looking for a pen that will be good fro sketching out in the wild and
don't want to take your more expensive rapidograph with you, this is a great pen
to do it. The ink is a nice cool black, and different from the other Uniball
micro tip pens but like the rest absolutely waterproof when dry. It also dries
I love this pen so much I just bought 3 refills for it.

This is my favorite pen. I would use an even finer tip pen if I could find one.
I use it for journaling because I like the way it looks with a full page of
I am very sad to see the blue color go away. I would like to see more colors,
not fewer. It would be even better if this company would make this tip
available in a more substantial, aesthetically pleasing body or really great to
see them make the refill to fit other companies pens.
If everyone would write to the manufacturer maybe this pen will not disappear
from the market.
I agree that it is not...
, June 8, 2011
I agree that it is not perfect but it is far better than anything I can find
that even comes close to the detail this is capable of. When it was new I had
little trouble with it not flowing consistently. It is about out of ink and it
has more dry spells. I am ordering refils. I also have a red pen that I don't
use much. The red one is the same age and is almost full. I have yet to have any
trouble with the red one.
I use this for writing in between the lines in my Greek Bible, so many words in
the new testament are only used once, twice or three times in the entire New
Testament I need a crutch.
Everything has its use......
, December 14, 2010
Everything has its use... this pen I've found to be a great substitute for
pencil sketching. It works very well when you make lots of short strokes when
drawing something, and like a pencil its tone varies considerably. It is indeed
"moody" as one of the other reviewers said, but this is another word for
"variable tone", which you can use to your advantage if you learn its workings.
The thickness of the ink can vary from very, very light, to a little thicker
than the 0.25 Hi-Tec-C.
It's not very good at all for making big, long straight strokes - you want the
0.25 Hi-Tec-C for those.
It's also probably not great as a writing pen, since as I said, it's more for
short sketching strokes, and writers tend to write each letter without taking
their hand off the page... the other coloured inks of these 0.18mm models come
out a lot more readily than the black, and are probably better for writing.
It's a pretty good pen...
, September 25, 2010
It's a pretty good pen with some drawbacks.
The great thing about this is its fine point. It's about as fine as you'll ever
need a pen to be. It's really great for getting really small details. As for the
pen itself, it feels and looks really good. It's also pretty cheap so it's worth
giving it a chance anyway.
One bad thing about this pen is the tip. I had to hold it almost straight down
to get a really good ink flow and even so it's scratchy on the paper I used. All
in all though it's a pretty decent pen for doodling and great pen for fine
I really WANT to like...
, August 9, 2010
I really WANT to like this model. I love really fine points; as a professional
calligrapher, I find all kinds of strange uses for this kind of pen.
But I find the 0.18 somewhat difficult to use. First, it feels predictably
scratchy (I just wish someone could solve this obvious problem). Second, the ink
flow is far from steady--I've had no blotching, but it's decidedly moody about
stopping and starting. Third, the sharp point slices right through correction
tape and liquids. Honestly, it's more of a pen that you own because it exists,
hoping it'll prove useful someday. Like if you need to protect national security
by jotting down something on that handy grain of rice. Every CIA operative needs

, March 20, 2009
i gave it 4 out 5 stars...and 4 only because its IS the worlds smallest, after
all! as for how it writes, well its not good for everyday use, however its
wonderful for drawing small details. feels very scratchy when you write with it,
but when you use it slowly, its great. a must-have for pen lovers; at least
until an even thinner, even more rediculously small nib takes the new
"worlds-smallest pen" title!
I was hesitant about...
, January 24, 2009
I was hesitant about buying this pen for a while, but I finally ordered one and
I think it is amazing. I think if you enjoy writing very small or making fine,
detailed drawings, you will enjoy using this pen. Otherwise, I think this pen
might not be as appealing. It works extremely well for a point that fine. I
think I'll get a lot of use out of it and look forward to picking up a few more
As everyone said here,...
, November 26, 2008
As everyone said here, a few other things however.
- If you drop it on the tip, it pretty much dies. This has happened with 2 of my
pens, so be careful.
- Ink runs out very fast, and it does drag terribly...
- Slightly lighter than the 0.38 I've used, but not really all that noticeable
unless you're looking at the paper a cm away.
- Definitely not for everyday writing, sketching is okay, but the ink goes out
rather fast after I'm done with drawing a picture.
- I find it best if you write with it upright... sometimes it annoys me but you
get used to it.
I reccommend the 0.38 for everyday, and I have yet to buy the 0.28! â™¥
BEST PEN EVER!!! Perfect...
, October 17, 2008
BEST PEN EVER!!! Perfect for fitting everything you learned on a cheat sheet for
school. the tip never broke or bent. (i write kind of hard) the color wasnt
bright, but you can still see it, being the tiny tip that it is. not to be used
with carbon copy papers. the tip is way to thin for that. you wont be able to
see anything on the page. Overall... the BEST PEN EVER!!!
The uni-ball Signo bit...
, August 28, 2008
The uni-ball Signo bit is indeed the world's thinnest pen. It is however not an
everyday sort of pen. The nib is just too fine. Wider nibbed versions of this
pen may be better suited for everyday writing, but I do not have any experience
with any other Signo bit other than the 0.18mm version. The pen is rather
persnickety. It of course drags the worst of any gel pen I've ever used due to
it's tiny nib. It also takes this pen a bit to "warm up". It seems to right
better after have written a few words but once it gets started it seems to write
well. The sizing on the paper also plays a factor here, as it does with every
gel pen. The more porous the paper, to a degree, the better the bit seems to
For a "stick pen" the bit is a bit short. When writing the end of the cap rests
in the upper part of the web of my hand. I don't like the feel of that. The
rubber and ribbed grip area is alright, affording me a good grip. Lastly the ink
supply seems to me to be a little shy. Overall the bit is a nice little novelty
pen but not a very good every day pen, at least in the 0.18mm size.
They are extremely fine.
, July 19, 2008
They are extremely fine.
REALLY FINE. It's fun to see how small one can write with them.
They are rather scratchy though, and it feels like they get thin and then
thicker, so the consistency is not that great.
It is good for a novelty pen, but I won't ever see myself actually writing with
this on a regular basis.
These pens are great!...
, May 18, 2008
These pens are great! You can write so small with them (actually works on rice).
For some reason the blue is a lot thinner than the black, but they are great. A
lot of people said that they break easily, but i found that not to be the case
(and i write pretty hard). I would definitely recommend them.

, May 12, 2008
they are totally awesome!! i just bought them and fell in love with them!! they
are perfect for taking notes in class and writing in planners... the only
problem i have with them is that their ink kinda runs out alittle too fast...
one week of intensive writing class notes and i need more refills...

, March 24, 2008
they are incredibly fine however, they are not smooth at all. the pilot hi-tec
c's are much smoother and with only a .25 point they offer the same precision.
as always jetpens has excellent service and care.

, April 5, 2012
I was very excited to get this pen but frankly I was extremely disappointed.
Although the pen tip is extravagantly thin which I like about it, it barely
writes. The ink only comes out for portions of the time which really makes this
pen inconvenient and hard to use. Truly a waste of money.
