The best pen I've ever used!
This is hands down the best pen I’ve ever had. It writes incredibly smoothly, never skips, and the ink is a beautiful, rich black – deep and crisp. The fine tip gives great precision, making writing a real pleasure. I loved it so much I bought a second one and stocked up on refills (3 blue and 3 black!). It’s no surprise this pen won an award in a Japanese stationery competition – it truly deserves the praise. Highly recommended for anyone who loves a high-quality writing experience.

Low ink
Amazing quality but ran out of ink incredibly quickly

It's alright, I like the build quality and the look. But the click on the One F is not as satisfying as the click on the One P and you can hear the spring squeak/ping on the One P but it's not too bad.

There's a reason Uni-ball has won awards for their inks. They're so deep and inky, they write so smoothly, and they really stick to whatever paper you're using. They might still smudge with something glossy, but for your standard stationary, there's few better pens to rival these.

I have been using this pen for a few weeks now. I have to write a lot in my job and it has been perfect. I like the feeling of this pen and while it does not glide like a 0.7mm the 0.38mm tip writes well and isn't too scratchy like some others I've used. The ink dries quickly so smudging is minimal.
