Uni-ball Signo RT1 Retractable Gel Ink Pen, Ultra Micro Point 0.28mm, Rubber Grip, Black Ink, UMN-155-28, Value Set of 5

love these pens, they are my favorite for writing in my tiny moleskine dayplanner. simple construction, nice smooth ink flow but fun scratchy feeling when writing, ink is dark and never smudges. comfortable to write with with small hands. lines are crisp and super thin, great for drawing small things with lots of hatching. pen click when you retract it is nice as well. big fan, have been ordering replacement ink cartridges for my original ones for a couple years now too so they are pretty durable. only gripe is the refills always seem underfilled but thats not a problem with the pens themselves.

I usually use a 0.38mm tip so it took me a while to get used to the 0.28mm tip but now I use it all the time. The pen writes smoothly and dries quickly.

The ink quality is not good. May be it is dry. With 0.28 tip i wanted to try it. It has a feeling like when the refill is about to finish

0.28 kalemin en zarif hali. Hafif ve pürüzsüz yazmak bu kadar keyifli olmamıştı

I'm one of those people who has an unusual obsession with office supplies. As such, I have tried numerous pens in hopes of finding the ~perfect~ pen to use in my everyday life. These are not the ~perfect~ pen; however, they are pretty great regardless. They are comfortable to hold and use thanks to the rubber grip, and the tips are SUPER fine as promised. After using Micron pens for the first time, I found that I favor pens in the .25-.4mm range for writing as the lines are finer and cleaner, and these definitely meet that expectation. So far, I haven't had any issues with bleeding, smearing, skipping, etc. I think it's because the ink comes out so thin, it dries before it even has a chance to smear; but then, I'm also right-handed, so unless I'm especially careless, I don't have many opportunities to smear my writing. I will say that, because the lines obviously come out thinner and therefore somewhat lighter than .5+ pens, people with poor eyesight may struggle to read things written with these .28mm pens, but I wear glasses so it doesn't bother me. Price wise, I think that these are a good deal. They cost about the same amount as the Papermate InkJoy gel pens and Tul gel pens I've been using, but you get more in a pack and the quality is great. Plus, anything finer than .5mm is frustratingly hard to come by. I definitely recommend giving these a try.
