MUJISmooth Gel Ink Ballpoint Pen Knock Type 10-Pieces Set, 0.5 mm Nib Size, Black

These are great pens, comfortable and smooth writing with a decently fine point. The clicking mechanism is satisfying as well. Muji does a good job

I’ve been using Muji pens for years, and ordering them on Amazon just makes it easier to restock. The design is sleek, minimal, and exactly what you’d expect from Muji. They write incredibly smooth with no ink smudging, and the fine tip is perfect for detailed notes, journaling, or planners.

Best pens!!! dark ink, smooth writing and they click, what’s not to like! No notable smudging noted and the 0.07 is pretty fine producing clean writing.

Love herrrrr, very smooth and doesn’t skip

Theses write so beautifully , I only use these pen good for high school and college students

Best pens ever. The .7 and .5 actually showcase a HUGE difference. The .7 are still great, but the gel and amount of ink that comes from the .5 is unmatched, for drawing or writing these are the best in the whole world

True confession: I am a pen addict. I used to buy pens every other week, never really being truly satisfied with any one. These Muji retractable pens have been the only pens I've ever used until it completely ran out of ink. I love them so much. They are not perfect for everyone. When writing in my Hobonichi, the ink does stay wet and can smudge. I get mad but it doesn't stop me from using these because they feel so good to write with and the ink, even at a .5mm is beautiful, bold and crisp. I'm not sure if I got a rogue set but when I went back to try a Muji pen with the cap and the ink looked much more dull. I'll definitely have to try a few more sets before I can declare these the best pens of all time but for now, I am a fan.

I normally write with pilot g-2 pens because I love the bold black. These pens are are well done. The ink doesn't form a little tip on the pen like it does with pilot pens and it writes very smooth. I love the minimalist look to it but since it doesn't have a grip. Not a huge issue when writing but significant. It also doesn't hold up to drawing long lines across pages, the pen seems to "run out" of ink until you lift it and go again.
