When the ink runs out, they can be easily refilled. Easily know the ink levels thanks to the clear frosted pen body.

    Reviews

    Bought every color possible because I loved the black one so much

    "Echoing the title, these pens are a nice way to write with different pen pressures and thicknesses. I use these pens for my pen art and shading and they do very well."

    — Erika N. (5/5)

    The perfect pen

    "Literally my favorite pen, this is such a good pen. The lines are so clean and also great for sketching. I can't stop having to refill because it is the only pen I now use. This is the best pen I have ever used and I am not sure I can go back."

    — Caroline S. (5/5)

    My favorite pen to date!

    "Haven’t been able to use any other pens since trying this one. It writes so smoothly and seamlessly no matter how sloppily or heavily I write (I tend to bare down when I write). And, it lasts long!"

    — Zainab M. (5/5)

    The smoothest pens

    "I give these away as gifts because they are the smoothest, just juicy enough pens. Couple the pen with a muji notebook and you’ll be in writing heaven 🥰"

    — CRYSTAL A. (5/5)

    The Best

    "LOVE these pens. They write well, are attractive and are reasonably priced. My only complaint is that the black refills are almost never available. Obviously the market is there, but maybe not the marketing department?"

    — Donald S. (5/5)

    The pillow is very soft.

    "The pillow is very soft. I use it for pregnancy pillow to provide extra support. The pan is very good as usual. I have been used at least 20 of them."

    — Yaoyao C. (5/5)

    Amazing!!

    "Used these for extensive notes and they stayed vibrant and juicy!! Definitely recommend!!"

    — Ava A. (5/5)

    Gel Ink Ballpoint Pen Knock Type 0. 5mm

    "Pen writes well. I also like the design aesthetic, and receive compliments on it occasionally. The body of the pen feels slightly soft though, so it may bend a little if you have a really tight grip. The tip also is quite sharp, and can tear the paper if it's on a hard surface and you apply above average pressure (I work in reception and would guess maybe 20% of the people that write with it have this happen. ) I also ordered two pens, but only received one."

    — Joel P. (4/5)

    Muji 10 pack pen review

    "I LOVE these pens!! at first I bought one pen, then I bought another and then another and eventually I decided to just buy the whole pack!! It's so efficient and lasts a long time for me, it's the best pens to use and all the colors are both so cute and useful!!"

    — Alondra R. (5/5)

    "I think of getting pens at muji as one of those undeniable little treats that makes life delicious."
