Really enjoy this pen!
Comes in multiple point sizes (0.38…0.5 micro…0.7 fine…1.0 bold). Also comes in multiple ink colors (my choice is blue/black, next is black, blue is a little light at the .05 point, and red which is even lighter at 0.5 point. Comfortable in hand, generally won’t run or smear (I am not left handed), ink in pen lasts quite awhile! Overall a five star pen that is disposable when empty at a good cost per pen when you get 10 at a time.

Great pen, good ink, nice fine writing tip. Long!
I got these after reading a recommendation and they do fit the bill. Nice pen, good for writing notes, journal, business etc, no spilling or smudging.Just one thing - these are the longest pens I've ever used, don't know why the barrel is so long, but I got the hang of it after an intial head-scratch.Recommended.

Good quality
I am using the Uni-ball Signo UM-100 Gel Ink Pen - 0.5 mm pens for over 20 years. They fit perfectly my hands and fingers. They write thin and don't leave any marks or ink on the paper. In plus, they have a nice color, be the blue, the red or black or black blue.I wish there were less of the same colour in a pack, and instead 3-4 colours in the same pack.I couldn't find them in any stationary shop only on Amazon and online.Anyway, I love them.

I always love this pen
This has been my favorite gel ink pen for the past 10 years. The only shortcoming is that they are expensive.

Used to be a good product but…
I used this pen for over 10 years. Bought another dozen but it came as sharp edges on the side. Some plastic dust along the body as well. Ink feels so dry and sticky. Not sure what happened…

and the weight is perfect. However
Expensive pen, but writes smooth, and the weight is perfect. However, the ink does not dry as fast as other pens sometimes, and it's easy to smudge if you're not careful. I use these everyday for school and for homework, definitely recommended for the college or high school student!
