Love These Pens
"⭐⭐⭐⭐⭐ I absolutely LOVE MUJI pens! They write incredibly smoothly, the ink is consistent, and the fine point makes my handwriting look so neat and clean. As a teacher, I’m constantly writing—planning, grading, taking notes, making lists—and these have quickly become some of my favorite pens to use. They’re comfortable to hold, don’t feel bulky, and the simple design is perfect. No skipping, no messy ink, just a smooth writing experience every time. I completely understand the MUJI pen hype now. Definitely a 5-star purchase!"

Blue black ball point
"They are very nice. Sleek design 0.5 mm tip with fine writing. They just haven’t labeled any pen as blue/black. They all are the same."

Best pens for the money, no question
"The rate at which the ink dries in the 0. 5 and 0. 38mm tips is great and smudge-free. I have used these utensils for over 5 years and havve only needed to replace those which I hav e misplaced. The 10x variety pack used to be my go-to but now I only buy refills. The cap is satisfying to open and close, the clasp has stayed firm after years of fidgeting, and the precision is second to none. Perfect for annotations, fine details, subscripts, etc. Love, love, love! I always scramble to find one of these when I need to jot something down. A must-have in any desktop arsenal."

"My favorite pen in the whole world! I was given one by a coworker last year and kept it. It finally ran out of ink so I had to get more. There's no other pen that writes quite like this brand and they are slightly harder to find online so you have to buy from MUJI! Will by more soon."

Reliable, vibrant, and perfect for notetaking
"They write smoothly, are very comfortable, and work with almost all barrel type ink refills from Sarasa dry to Pilot G. The Muji ink plays nicely with many paper types, from high end to cheap copy paper. They smudge a little bit on nice paper, but they dry within ten seconds. This is typical for lefties like me, and I just learned to become an overwriter. I recommend for the clear pen bodies alone, the ink is a nice plus."

Awesome!
"I have so many classes that I have to take notes for, and these pens are perfect! Especially for AP courses, since you can only use blue or black ink. They’re very handy and having a set of 10 means no running out for a longgg time."

LOVE these pens
"The . 5 pens were so amazing I had to buy the full pack after trying 2 individual ones. I love the colors and the consistency. These write so smoothly and don’t smudge or skip on the page. Journaling and working has been so fun with these!"

I’m a “pen guy”. I love these.
"I have tried, bought, and collected DOZENS of pens in my career in design. Nothing comes close to the superior drag, flow, and depth of color achieved on the . 38, . 5, and . 7 ballpoints from Muji. Truly a game changer. I use the inserts in these to refill my premium more expensive pens as well. A fantastic design and experience, especially if you like to feel the tooth of the paper under your pen without missing or skipping. Love em."

Wonderful pens!
"They don't write too thick and have a consistent width to the letters, which is great because I write tiny. I write on paper a lot, so these pens are very nice to have."
