This pen writes smoother than a jazz saxophone in a bubble bath
I don't usually get emotional about office supplies, but these Uni-ball One pens? They changed me. The ink glides like it's on a mission from the handwriting gods. No scratchiness, no hesitation, just pure, silky lines that make my grocery lists look like calligraphy written by a monk with perfect posture. The 0.5 mm tip is sharp enough to slice through my existential dread but gentle enough for even the most fragile Post-it Note. It dries fast too, which is perfect for lefties, impatient people, or anyone who’s ever accidentally dragged their hand across freshly written text and ruined both the paper and their will to live. The clip is strong, the click is satisfying, and the pen feels expensive enough to trick people into thinking I have my life together. I bought the 12-pack so I could lose 11 of them slowly over the next year like a true adult. If you want a pen that writes like a dream and makes you feel 10% more competent, get this. Then write a thank-you note to yourself in perfect, smudge-free ink.

One of the best pens you can get regardless of price!
I absolutely love this pen. Extremely comfortable to hold. Looks fantastic and a joy to write with. The secret is their ink. I don't know what their formula is but it's going to be one of the best writing pens you will ever own. I have expensive pens that does not write as well as this. For the price, you can't beat this!

Good pen!
Overall great pen. I like the ink quality - however, it is a bit inconsistent. Some pens never have “gaps” and some have frequent blips in the ink. I may have gotten a bad batch.

Lays down a sweet line!
Well, I liked just about everything with this pen. As a pen junkie, I'm always out on the lookout for the pen that lays down the smoothest, darkest line, with no clogging. Should be comfortable to grip (a little texture, not too much), have a good clicker and ideally, not have a pocket clip that will tear your shirt putting it in and out of your pocket. Oh, and look sharp. A white pen! Nice change of pace. THIS IS THE ONE. All criteria met!!

Hard to get tip wax off
Hard to get the wax off the tips so you can use the pen.

I can see why this pen won stationary awards
Bought them after seeing they won stationary awards in Japan. Been using them for almost a year now. Really nice pens for their price. Would buy more if I ever need another box. -The clip is kinda like a spring mechanism and works well, hard to break. I've clipped them onto folders or pockets and they return to original position even after months. -There's a bit of a rubberized covering for a comfortable grip. -Ballpoint writes smooth and easy. -Pen to pen is consistent.

For buttery smooth writing , 0.5mm is a personal favourite.

I purchased these on recommendation from a friend, and looking at options for my child who is left handed. The ink flows really smoothly, making them good for lefties and doesn't smudge too much (though still a little). They're quickly becoming my favourite work pen also!

These pens don’t smudge and are very light and don’t dry out like most pens I’ve got online.
