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

Of course, my opinion is subjective, but I am happy with these pens when it comes to writing in my Bibles. I have tried the Pilot P-500 and Micron pens and these Signo pens are by far my favorite out of those three. A lot of my preference likely has to do with my own writing style, but I can make much neater and just as small print with these pens as with the others. Plus, these are not as expensive as the Microns. I can on here to order some more today and thought I’d share my experience.

Amazing pen if you need to write small and still be able to read it.I work as an intensivist in a busy MICU and of the substantial number of pens I've used over the years these are by far the best for small detail dense writing. I like to keep a single sheet of paper with me for my patient list and having the ability to pack everything I need to keep track of in a small section of the page only really works with these pens. I have tried 0.25mm pens however they either write too faint or actually cut the paper, something that has never been an issue with these 0.28mm pens.Plus the gel ink dries quickly, the pen head glides easily over the page, and the stock pen body is comfortable in hand. A very good value of a pen that out classes ones costing ten times as much.

I'm constantly on the lookout for the best pens I can find that are super fine tip. I generally land on micron pens because of the 0.20 fineliner they carry but they aren't the most comfortable to write with for long periods. I was super excited to find these 0.28 tips from uniball signo but admittedly didn't have high expectations and expected alot of skipping. I've used three of them out of the set I bought and they haven't skipped a single time. Comfortable to write with over extended amounts of time. Everything I was looking for in a pen. 10/10 recommend and 100% will repurchase.

Amazing pens !! Love to write with them everyday at work.

Perfect

Great line and ink in these. Truly fine and precise without much skipping on thirsty or toothy paper. Can be a bit straggly. But overall, I love the quality of the pen cartridge itself. It's great to draw with.I find the pen body itself to be somewhat bulky and awkward. The lowest part of the barrel right above the pen point is very dome shaped. The end does not have an elongated taper like other fine point pens I tend to like. Pilot Precise V5 RT is one of my favorites, but their finest point is only 0.5. This pen is quite a bit finer, and I love that about it -- but I have a hard time seeing the pen tip while I'm working because of the large size of the barrel at the tip.Another reviewer added a photo of them writing with the refill cartridge on its own. I had actually done the very same thing when I first started experimenting with the pen. I just took it out and began drawing with it. The plastic on the cartridge is very rigid, so it's easy to use this way as a minimalist pen on it's own. The feeling of that is actually very precise and great. So if you're struggling with the bulk and profile of the actual pen body, the refill on its own is a neat option.My ultimate fix was to just put the Uni cartridge into a Pilot Precise V5 RT body. It works great. If you do this, you WILL need to loosen the threads a quarter turn to click the cartridge tip out. Then tighten. Then do the same to retract. It's no big deal, and functions normally with a quick turn (and click) -- similar to old mechanical pencils. Since this actually identifies which pen has a Uni cartridge on board -- it's a win/win as far as I'm concerned.Myself, I'm just used to a Pilot pen body, and prefer the more narrow tip and better rubberized grip. So for me, it's the best of both worlds adding this great, ultra fine cartridge to my favorite pen body. For me, the Uni vs Pilot body feels like the difference between a jumbo and standard crayon in my hand. Both could certainly be useful for different applications.Overall, I'd buy these pens again. The line quality alone is worth the time figuring out how to best use them for my own needs.

Love these pens! I have ordered them multiple times! I love the very thin and fine point! I use them every day for work, but could be used for trace drawing and other thin linings!

The General Surgery Residents love these pens.
