best pens ever
These write very smooth and last a decent amount of time! I also like the simple design

The modern Bic ballpoint that writes like a rollerball.
These are great. Ballpoint 0.5mm gel write like rollerball, but no smudging. Stiff body - only lacks grip cushion. Front unscrews for service of cartridge and spring. Positive extend/retract action. I've tossed that dozen or two ballpoints and rollerballs I've accumulated and replaced them all with these.

Amazing
These are some of the best pens I’ve ever used. It’s crazy because I bought the ones with tops a couple of years ago and didn’t love them, but these retractable ones are so much better. Almost everyone who uses one immediately wants to know what kind they are and where they can order them. They also dry very quickly and do not smear in my journal. Love them!

Good colours, quality & smooth writing.
perfect! good quality, i feel they will last me a while with little care. i've gotten 3 pens from the Muji store in Canada and they lasted me a good 8 months; with consistent use of them all at once, so im excited for these new colours!

Amazing pens!
Absolutely love the pens! I use them for note taking and they write so smooth. The only downside it that they do tend to smudge, but for me that’s not an issue since I don’t try to go over it with a highlighter right away. So if that isn’t a huge concern for you, I highly recommend getting. I’ll definitely be buying more.

Nice Japanese-style pen
I absolutely love this minimalist designed pen. It is the 0.5 mm pen which dries quickly but easy to write. The ink flow is constant and the pen lasts very long time. I gave some to my sister and she was so fond of it. It’s a little pricey compared to other pens but worth the Japanese quality.

THE BEST PENS
If I could give these pens 6 stars, I would. I borrowed one from a friend for a quick second and fell in love with these. These are the only pens I will use. They write so smooth! I write a lot and these last a long time! I even had a patient borrow my pen and wanted one for themselves! I gave them 2 because they are the best.

These pens arrived early and were undamaged. They arrived loose from the internal packaging. The colours are amazing, the pen barrel is smooth which may take some time to get used to, however they write so smoothly with no skipping.
