Wrong description
Although the pen is described as 0.5mm, it is 0.7mm.

0.7 mm
The ball size for the pen is 0.7 mm not 0.5 mm which makes the font size wider and uncomfortable for me.

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.

Love these pens. Seem to glide as you write.

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.

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…

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