BEST PEN EVER
Not even exaggerating—never held a better pen in my life. Got red and black to mark up work and my studies. I highly recommend these pens, I am huge when it comes to how a pen/pencil feels in my hand since I like to take hand written notes for running errands/making lists/studying and I love how this pen does not leak, writes smoothly, does not hurt my hand after extended use. Really really hope they never discontinue these pens!

Fine line writing
These pens have been around for more than 30 years. They still work the same. Fine lines, and smooth rolling. I'll be buying them for years to come

Excellent
Love how thin the pen writes and without skipping. I can actually use it in my Bible if I don't press and it doesn't bleed

they write fantastic, they don't bleed all over
There's something about a pen that has the same design from the same company for over 20 years. They're low-cost, they write fantastic, they don't bleed all over, and you can't get a crisper line.

Best pen if you like to underline!
If you are like me, and like to underline sentences and passages in the history or guide books that you are reading, this red pen is the best I have come across. The ink is not too bright, doesn't detract from the text, and it doesn't bleed through the thinnest of paper. An excellent pen for underlining text.

Excellent value, very comfortable
I've loved these pens since I worked in State Government where the contract provided for a choice between these pens and cheap Bic ones... You can imagine which one I picked. That was nearly a decade ago. To this day, these pens have served me faithfully with precision and strength. Though the ink does run when it gets wet, the ink flows out of the pen so smoothly that I can write pages upon pages without any hand fatigue at all.

Tratto fine, scrittura fluida. Sono delle penne di buona qualità. Spedizione arrivata dagli Stati Uniti alcuni giorni in anticipo rispetto alla previsione.

I love my pens and have been buying more than needed lately. These are fantastic, nice glide, the ink doesn’t run dry on you either. Uniball has always known what they’ve been doing

Nice pens to write with, and very cheap. They leave a good line and I've not used any up yet. However, unlike most liquid ink uni-ball pens, the ink they use is water soluble! This makes it very poor for lab book use. However, I find it is only semi soluble and doesn't instantly vanish like some pens, and a quick test with methanol and acetone didn't seem to remove it more. I'm disappointed, so I guess I'll stick with the Vision line. Note: I found another pen that felt like this one, but with blank ink on my desk. It took both solvent and water fine, so it could be that the black ones are better for lab book use.

A few leaked after a while of use but I really like the output
