uni-ball Signo UM-100 0.7 mm Gel Pens, Black Ink, Pack of 12

Great pen, writes well, doesn't stutter, grip is decent but causes aches of longer use, ink flow is good enough, color is standard with no issues, great build quality, slightly expensive but still a really good product

I need again to buy.

Product is very good but price variation. In the product itself mentioned Rs 240 in Amazon Rs 300 extra 60 rupees they are selling I don’t know why. Per pen price is 40 then why they selling in high price. Very disappointed from Amazon.

Nice quality

Nice to use for rubber product marking.

Smooth ink Flow. Worth buy

A sticky gum type cover has been put on the tip of the pen ball as a protective cover. It is sticky and unable to remove it properly from the point and some residue of this sticky substance is stuck into the ball of the tip inside. Cannot be written properly as it slides with less ink/gel supply or flow resulting in light colour lines. There was no absolute ink supply when pen writes upper stroke. The pen is thrown into dust bin.

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 40 so if u r a person who doent care for the life and who cares about the quality this is the way to go

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

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.

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

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.
