Love this. Pen is a great thickness, grips very well, has a lovely click action and the clip can be squeezed open, which is a great detail feature (great fidget pen!). Carefully and thoughtfully designed. Fantastic value, excellent build quality, superb design. Included gel cartridge is very stable on page, though feels a little harsh due to the very precise and small tip - personally I love this pen for tasks like wireframing, sketching/annotations and other quick stuff, but others may actually prefer this feel for writing. Note that it IS a refillable pen, so you're not stuck with this if you don't like it. Overall, just a really handy, very well-made and eminently pleasant pen at a fantastic price.

The best pen I've ever written with
I saw an advert on these pens being "award winning" so as a stationary nerd had to get one. I was surprised by the price and really liked the colour options across the market. The writing experience is smooth and consistent whilst still comfortable to write with!

Such good quality
Me and my partner both got one of these pens to try, and they are just great! The ink flow on these pens are fantastic, the staggering/intermittent ink flow you get with some other pens I have never experienced with this one...its so impressive. The pens themselves have been used a lot, yet no sign of wear whatsoever, they are very durable. The ink is also perfectly just black, no visible blue undertones.

Uni ball one- small and mighty pen :)
Absolutely AMAZING pen I deffo recommend this pen! I have problems when I’m writing or studying. My hand starts to ache because I press down on my pen so hard. This pen is an amazing solution and I’ll tell you why - the pen stops you from gripping tightly -the pen is small so you don’t have much to grip tightly either. (It’s small but an amazing size to be honest ) Five stars from me

Nice pen, scratchy nib :-(
Lovely little pen though didnt keep but let me explain why. Its a lot shorter than normal pens, but whilst that was ok, i found the nib a little too scratchy for my tastes, I was expecting a 'smoother write' and maybe its my paper ( i tried a few different books) or perhaps i'm heavy on the hand, all that aside, its just wasnt for me. Have given it 4 stars as its a lovely colour and held nice, but the tip was too scratchy.

Writes like a dream
Uni ball gel pens are the gold standard 👌. No skipping and writes like a dream. Dries fast as well and I love the mint green coloured barrel.

shorter than expected, but rests comfortably still, lovely ink flow and girthy diameter
I was pleased that what I received was a genuine Uni One P import, and after using it for a little bit I've found that the girthier diameter of the main shaft makes it easier to maintain a secure hold for longer writing sessions - it feels like my finger muscles are less tense than vs thinner standard pens. The pen length is shorter than I expected at about 115mm overall, but I actually didn't find this to be an issue because it still comfortably rests in the nook of my thumb - any shorter and it would miss, and I have quite large hands. The gel within writes a lot more smoothly than a regular ballpoint - it's crisp and opaque and seems to have a nice consistent flow which is giving me even-width lines strokes,.

Overhyped unfortunately
It is a nice pen but it stopped writing fairly quickly (within a couple of months, it might just be blocked up or something but I haven't dedicated time to figuring it out) It feels quite scratchy on the paper in my opinion but the ink does dry almost instantly!

Good ink very compact
Pen is very nice smooth ink and a great thickness to hold however I didn't realize it would be so compact. it's a great pen otherwise it was some getting used to Holding it but other than that its great

Hermosa
Es algo cara, pero vale la pena. La escritura es fluida y seca muy rápido, por lo que se puede usar un marca textos sobre la tinta sin ningún problema. El único problema es que luego ya no la quiero usar para que no se me acabe tan rápido jaja.

Worth It
Ordered for the second time. One of the best Ballpoint Pens. But refill is the problem. Searched online as well but could not find refill for this.
