Uni-Ball AIR Micro - 0.5mm Fine Rollerball - Pack of 6 - Black - UBA-188-M

I had tried the bold version of this pen. The nib has a bit of give to vary line width. So I decided to order the Micro version and see how it stands up to the bold. So far, it's been great. The ink flows smoothly and dries relatively quickly. I've been stocking up on the uni-ball Air models just in case uni-ball decides to discontinue the model. Great for writing on thick paper has it has a tendency to bleed through thin paper if you let the pen rest on the paper for so long (a few seconds).

Originally bought these pens because a coworker bragged on how great they were and gave me one I had the one pen he gave me for a week and lost it and it became my saddest day ever, I bought my own and they are awesome for work they don’t bleed through anything they are perfect highly recommend them to all nurses

So as I was sitting across from my coworker I became envious of her pen. This thing is as smooth as they come and leaves no streaks. Very good quality. I do wish they had a little grip but other than that barely short of phenomenal

I think these are probably my most favorite pens I’ve ever used and I am a pen snob big-time these rides so smooth the ink does not bleed and they look fantastic

I love these pens! Super smooth writing, the ink just flows. Pressure sensitive, it doesn't feel like you're writing with a ballpoint, more like an extremely fine marker but it glides much smoother.These are my new everyday pen.

I was excited to find these! Had received one in a Cloth & Paper subscription box, but was a .5 or .7 thickness. I enjoyed writing with it, very smooth and bold. Worked well in my Hobonichi and Happy Planner. Saw these and felt they were a good value. Turns out they are a MICRO, which means they are thinner than the current one I have and it is even better! Not as inky and still very smooth. Love them so much.

I bought this pen expecting a smooth writing experience with minimal leaking and inconsistencies. Instead, I wasted my $10 on a pen that bled through not just my binder paper, but my Leuchtturm1917 notebook paper. In addition, the first pen in the package had inconsistent ink, where sometimes I would feel a scratching sound and no ink would come out. That pen also lasted just a week and a half before it ran out of ink. The second pen I used from the order seems to be better. Not as inconsistent, but the ink still jumps and it definitely continues to leak through the paper. Time will tell how long this pen lasts.

I was excited to get this from the reviews but I just finished covering a whole page in writing and I’m sad to say I was mildly disappointed. After a while it got a bit better but writting felt rough and the letters came out bumpy. I usually like uni ball pens but I don’t plan on buying this style again. I would not recommend if you care about the smoothness of how writing feels, but I guess they look cool?(In the picture, the bleeding is from the pen on the other side, with the pressure I normally write with)

Perfect!

I draw a lot, and write a lot in my day to day job. A colleague of mine had one of those pens and when I tried it, it was very different than any other disposable pens I tried so far. It's something akin to a fountain pen with a nib, but not exactly. Certainly a different writing experience than most cheap rollerballs or felt tips - not everyone will enjoy it, but for writing, it makes a very smooth, pleasant and different experience. If you are particular about your writing, try them! For drawing, not so great unless you do it on large format and very heavy paper. Your mileage may vary. When on sale, much cheaper than purchasing in regular office supplies store (where it was indecently expensive).

Nice pens, virtually no pressure required to write, as advertised. They are a bit of a thicker line than the 0.5mm uniball needle pens, more like the 0.7 needle line, personally, when casually writing with my typical pressure.As designed, this line thickness does vary with pressure, but, unless you are a very light touch normally, you will likely have to adjust your writing style/pen pressure should you want a thinner line.Doesn't seem to bleed any more or less than other uniball pens in my personal experience. If you are familiar and comfortable with this, this is what you'll get. A smooth, crisp, high quality paper will not bleed, and a rougher/softer, more fibrous sheet will allow some bleed.It is very much an effortless and smooth flowing writing experience, and the varied line thickness does create a nice effect, especially for signatures. I love it.

These are a really nice option for sketching. The tip is a little like a felt tip but very smooth the ink is permanent so you can paint over it and it won’t bleed. Much less expensive than microns.

I love the way these write. It’s liquid ink that comes out but it doesn’t bleed or make a mess. It’s very satisfying to write with these
