uni-ball Signo UM-100 0.7 mm Gel Pens, Blue Ink, Pack of 6

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.

This is a great pen but not cost effective , even if you use refills they still cost 25 but the ink flows really well and writing it feels effortless and a small detail which I really like is that the top of the pen which holds refill in place is machined stainless steel

Nice quality

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.

The Uniball Signo Pen is truly a joy to write with! Its buttery smooth ink flow makes writing effortless, gliding across the paper without any skips or smudges. The pen feels perfectly balanced in hand, and the fine tip delivers crisp, clean lines, whether for note-taking or detailed writing. The ink dries quickly, reducing the chance of smearing, which is a huge plus. On top of its performance, the design is sleek and comfortable for extended use. If you’re looking for a high-quality pen that offers a flawless writing experience, the Signo Pen is unmatched

It is a very smooth pen, however out of five, two of them were not working properly which i find disappointing, the ink flow and smoothness is good

Nice to use for rubber product marking.

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.

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

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

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!
