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

This pen is fantastic! It writes smoothly, doesn't scratch the paper, and makes the thinnest lines that I've ever seen in a writing pen while still being dark enough to easily read. Some art pens are comparable, but are not really meant for continuous writing like you can with these. I use the pens to fill out care plans and med cards in nursing school and they work nearly perfectly for pages of writing. Recently, only one of the pens that I have been using frequently started skipping slightly even though there's still a decent amount of ink in the pen. Other than that, they have been perfect, especially because the grip/soft area continues to the tip and is comfortable to write with continuously. I've never loved a pen like I love these pens. I'd rate them 9.99 out of 10 (0.01 taken away for the one pen out of the 5 that skips after writing for a while).

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.

I LOVE THESE PENS!! This is exactly what I was looking for! I'm using them in my planner and journaling. The writing is smooth and very fine but I can still see the blank ink. Definitely gonna get more when I run out. I'll see how long they last but so far they are great! I'm not sure about the price but seems reasonable to me.

These pens are the real MVPs of my shift. They’ve survived spills, pen thieves (I see you, night shift), and even being launched across the nurses’ station during “spirited discussions” over who’s covering lunch breaks. Ink flow? Flawless. Smudge-proof? As much as my mascara after 12 hours. And if you haven’t charted a full suicide risk assessment using one of these, are you even documenting properly? Honestly, these pens have more emotional stability than half my patient caseload—and they click, which means they’re fidget-toy approved. 10/10 would recommend. Already hiding one in my scrub pocket like it’s contraband.

I have been buying these pens for over 3 years now. I love the size of the tip, it's been great for journaling and writing in my bible. If you are looking for a good bible pen, these ones are great. They do not bleed through the pages. The one "complaint" I have is that the ink doesn't last long. When I was journaling daily, the pen gave out after about two weeks. That's never bothered me too much because I have kept quite the stash of these pens. Highly recommend

I just started urban sketching on location and needed a no-fuss pen (always works, quick drying, no pen caps to lose). This pen is perfect. The click mechanism is why I'm using this pen vs my usual Micron pens. Ink flow is very consistent across various angles. The grip is nice, not slippery when wet.

I love these pens. The ink flow is good, no bleeding on my pages, very comfortable in my hand. I like a very fine nib and this pen doesn't disappoint.

Writes great, love the thin tip.
