Signo UM-151 Gel Ink Pen Black, 0.38 mm, 3 pens per Pack (japan import) [Komainu-Dou Original Package]

This was my first time trying the Uni-ball Signo UM-151, and I’m officially converted. I’ll be switching over from my longtime favorite, the Pilot 0.5. The Signo has a nice weight, writes incredibly smooth, and the 0.38 tip gives me the precision I didn’t realize I was missing — perfect for detailed writing or small notes. The ink flow is clean and consistent with no skipping or smudging, and it feels balanced and comfortable in hand. I’m impressed with the quality and control — this pen just makes writing more satisfying.

These are well made rollerball pens with good ink flow and a small tip that allows me to write smaller that I might normally. There are a number of colors available.

These pens write very nicely.

I am a pen snob with a B.F.A., and have been turning into a snob, slowly, over the last 15 years. The pen in the photo advertising this pen shows Japanese writing on the top end of the pen cap. The pens I got do not have that, and read "uniball Signo DX 0.38". If that sounds like I am being picky, fine, I just told you I am a pen snob. I wanted to see the Japanese writing on the pen cap to reassure me that these were indeed a genuine Japanese product. My money- my complaint.

smooth writing feel. i needed something for notes in a small square. i was using the uni micro 207. that was good, but had the issue of mild ink feathering. this pen does not seem to feather like that which makes it ideal for those very small notes. they are still readable.

I use this pen 90% in my art work. (Use it after watercolors as it is not waterproof.) it’s smooth and flows with rich pigment.

These are by far my favorite pens, I've ordered them before and I plan on continuing to do so. Super fine point, and they write really well as long as the surface isn't too hard (sometimes they don't write well with just one sheet in between something hard like stone, for example, however that's just the price you pay for a .38mm ball). Highly recommend you get these. I originally got them for writing equations and circuits (since you could add really small details with them) but now I use them for everything.

Love them. Nothing fancy but if you are needing a pen that writes with a very fine point, look no further!

If you like a super fine point without the scratchy feel, this is it!

These are my absolute favourite pens. I have been using them for the last ten years - all throughout my Masters and PhD. I love how fine the point is and they're reliable with ink. And the fact that you can get them in a variety of colours just makes them ideal.

Love all Uniball sign opens. I use the .38 For very fine lines and the broad tip for mark making . One of the best I have found!

The best fine-point pen I know of. The ink wells could be more full, but it's worth it anyways for the quality of the tip.

My favourite pens, I keep re-purcharsing them! Definitely recommend!
