Great!
I was anxious it wasn’t going to fit because it looked different online vs the ink cartridge that came with my uniball ONE pen. Fits perfectly! Ink flow is great just as good as my first refill. I LOVE this pen so much. Nice to know i found good refills.

Very good deal compared to replacing pen
Been through 2-3 of these so far, mostly to replace the barrels in my Uniball One P’s. It hasn’t been long, but I do take a lot of notes sometimes. I say I can go through one in a week or so if I go at it. Thus, this is a great deal at about $1 a refill and a much more economical choice than replacing the entire pen. The refills look just like the ones that came in the pens, only with a different stamped date. Furthermore, the ink is just as dark as the original ones and write just as smoothly. These will make my favorite pens last forever and won’t break my bank.

Worth getting refills if you like fine tip pens
The box these refills come in came damaged and flattened, but that is probably the delivery guy's fault.The refills are fine and they do the job. I put them in my uniball one p and it's great. The ink does skip a little sometimes but it's not that bad and kinda to be expected with such a fine tip. Only con is they run out pretty fast so the refills are definitely something you should have on hand. I think they're worth the money and they fit great in the pen.

Works Perfectly
Although the ink runs out quickly, that is not the fault of the refills. They work amazingly and allow me to use my favorite pen.

Love uniball
So I love my uniball one p pens. Well, I accidentally broke the tip to my new pen. So I purchased these to have extra just in case. Well, at first I thought they wouldn’t fit, since the pen is so small. Haha it definitely fits. So happy that I can use my pen again. I would love it if they sold different color inks for them also.

Great deal on refills
These refills work well for uniball ONE pens. It is easy to insert the refill cartridge into the pen body. The 10-pack of refills is a great deal financially!
