Flawless and thinnest writing experience possible!
A lefty’s dream come true! No bleed, no smudge, perfectly smooth ink for ALL colors. I have no notes. I wish I had a million of these and never had to use another pen. The black is classic and I’m blown away by the smoothness of these colors! Please never stop making these, Uni-ball!

Great Product
This product is a fantastic find! It's reasonably priced, making it accessible for most budgets without compromising on quality. The product is exactly as described, and its usefulness cannot be overstated. I've found it to be incredibly practical and efficient in meeting my needs. The attention to detail is impressive, and the performance is on par with more expensive alternatives. If you're looking for something reliable, well-made, and at a fair price point, this is the perfect choice. Highly recommended!

Game changer for Left-handers!
I’m a lefty! If you are too, I feel your pain. These pens are amazing! No smearing, which means the entire side of your left hand won’t be completely covered in ink after hours of note taking! We also write teeny tiny. The pens are so sharp and smooth it makes your hand-writing incredibly neat and precise. The best part is, it’s not limited to black and blue! The blue comes in 3 diff shades, although I do feel like the lighter colors in the pack are not intense enough to write but they are fine for underlining, starring, etc. The purple, black, red, and dark blues (2 diff shades) are all great! 10/10 for the lefties. I’m about to make my 4th purchase. I’m officially addicted!

They didn't send all 10 Pens! I only received 8!😫😫😫
I LOVE these pens! Let's make that clear! But like someone else who wrote a review, and complained, I also received only 8 pens from this merchant!!! I don't know what is going on here, but I was shorted a PINK and a BLACK pen, leaving me with only 8 in my set. I wasn't very pleased with that!!! I contacted Signo directly, but never heard back from them, so I'm not certain who's responsible for packaging the sets...Signo or, the merchant. I love writing with these pens! I have extremely small penmanship! It's not much larger than this lettering. The only thing I could ask for is more ink in the pen, to begin with.🙄 The Hi-Tech 0.25 that are my absolute favorite, have ink that extends over an inch higher (I measured). These color pens have ink which only measures 3.25" up the length of the 5.50" pen. It won't stop me from purchasing this pen, after all, I love the consistent quality of the line width between the colors... That had been a problem with another brand before🤔. The pens are comfortable to hold, which is important, if you have arthritis like I do! The main complaint I have, is they aren't sending out what they are posting on the website on Amazon! I'm NOT the first to complain about this! The merchant needs to update the posting on Amazon, or send out the 2 pens to EVERY single customer who was shorted. Happy writing!🖊

These are the best pens if you like micro point
Fun colors and the tiny points mean you can write a lot in small spaces. So far, no leaking, no ink interruption, no ink blobs, and they flow so smoothly and consistently. They are sturdy and not slippery. I hope they never stop making these micro point pens.

Fine and clean!
Outstanding product. Uni-ball makes exceptional gel pens especially the ultra fine ones. Poor shipping: Ordered from DRAWER PLUS.

Its hard to find 0.28 pens I love 0.28 pens! I used to use the uni style fit 0.28 but they are also hard to find and this is quite similar,I am happy I have found these! I hope they continue to make more. So I can purchase more when they run out. Thank you!

These are the nicest 0.28 gelpens to write with. They are not scratchy. The ink colours are true to the body.

The Uni-ball Signo in black (.28) is my favourite pen to use when I want to neatly pack in a ton of info into small spaces (which is often hahah) so when I saw this pack of varied colours, it was a no-brainer. A welcomed addition to my pen collection! They ARE a bit scratchy - but I love that so it's not an issue for me at all :)

I rrreeeaaallly hate writing and I have finally found pens that take my fancy. They feel incredibly cool to write with and I don't really understand why. I think it might be how thin the tip is because I've never really enjoyed the thing ones, not even back in school. I highly recommend these to anyone who prioritizes the feel of a pen when writing.

I LOVE these pens! If you like a very fine point pen, you will not be disappointed. I’ve used the black ones for years and was excited to find them in a range of colours! Warning: once you use these you will never be able to use any other pen again!
