Mitsubishi Pencil UMNSFT05D.6 Gel Ballpoint Pen Uni-Ball One F 0.5 D Green

The pen came as pictured, writes super smooth on all types of papers with really dark a pigmented black ink. Pretty colour and super cute for things like note taking, journalling etc.

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.

手にしっくり来て書きやすい、インクのつきも良い。ってところの他に、クリップが壊れづらそう（上を押すと下が開くタイプ）だったので嬉しかったです。

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.
