Signo UM-100 Gel Ink Pen - 0.5 mm -10 Pcs (Blue)

Writes well, good color of ink; and it will last a long time unlike some pens.

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 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.

If I could give a half star I would. I work in the healthcare field so I’m using pens all day and I can honestly say this was by far the worst purchase I’ve ever made in my entire life. The pen busted on the third day I used it and went all over my white coat and hands. I literally grabbed the rest of the pack I bought and dumped it in the trash. I wouldn’t waste your time or money on this terrible product

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.

I love this style of pen, however it is way to fine. I was looking for a "bold" or at least "medium" .

when i was secodary school iwas useing then it disable i search in Saudi Arabia not find i gite it amazon very good thank you it is best pen i see and use

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

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

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

ok first,i was super excited abt having a uniball pen because i know its going to be a stand out product from all other pens.so i purchased it and i really had a good exerience with this pen.this pens ink is so vibrant and smooth.it jst goes on i cant describe how the quality of ink is actually.the pen body os quite sturdy and the front knob is actually of steel or aluminium which gives the pen quite mettalic and sturdy feeling.the reason why iam giving three stars is due to the fact that the ink completes so fast .afer jst writing a medium size page almost the ink level decreased by 2cm.so literally a minimal use of the pen only gives u about 5 days of life which is actually not good given that the price of each pen is 40so if u r a person who doent care for the life and who cares about the quality this is the way to go

This is not a very smooth pen. I was expecting that like the other unibal signo pens this will also be a good one. But if you compare with pens(smooth one - pentel gel pens) this is not that that great. Also, it is not worth for 40Rs/pen.

Sometimes the ink is clogged.Other things are fine.
