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!

    • Nice Writing experience.
Color: Blue
I love pens and writing utensils, just a personal hobby of mine. I came across these while on a trip to Asia and bought a pen fro the Muji store, it was a wonderful writing experience. Had to buy a box of these when I got home, super glad that Amazon had them for purchase. Writing is smooth and the ink is high quality, doesn’t run or smudge and just feels good to write with. Ones are comfortable to hold in the hand too, I’ve only used the blue and black options which are fine for me. ... show more

The pens are very smooth and I love the nib size! I had one before so I bought a pack once I started running out.

    • Nice Japanese-style pen
Color: Black
Review Image by Tony Tony
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.

    • Love these pens
These are great gel pens, and are akin to the previous muji gel pens that had a cap. These are nicer because you do not have to worry about losing the cap, and it is easy to switch colors- great when using the colored pens to mark up documents. Compared to their previous clicker gel pens, these also are nicer- something about the frosty plastic is smooth and comfortable- the polycarbonate of the older clicker pens I did not like. They are also less bulky then the old clicker pens, with their profile resembling the capped gel pens. I like that you can see the color from the top. These all right very smoothly and they all came with the red "cap" on the tip so I knew they were new. My only complaint was that there may be low product control. The sky blue pen does not work, and it appears that there is a gap in the ink, which hopefully will resolve as I keep it upright. But the level of ink in that pen is maybe half what it is in most others. When I put them all side by side, most are "full", two are maybe 85% full, and the sky blue is maybe 50% full. It doesnt bother me enough to return the pens, as there is no guarantee I won't get another color that is defective (and more important to me). It seems like some other reviewers have experienced similar things, and it is unclear if this comes from muji and is a general issue or somehwere else along the supply chain. Overall, I will never need all 16 colors at once so I am not too concerned, just annoyed. All other colors flowed well, and when I noticed one of them seemed to be hit or miss, I realized that a piece of the red tip protector was still there, so once removed, the issue was resolved. These are pricey, but I knew that when I bought them, and there is a reason why these are so popular and iconic. They, along with pilot colet-c, are the two smoothest gel pens I have experienced. ~~~ I just bought another set, so I can have one at home and one at the office. The second set came with all pens working, all filled to the same level, and overall better packaged. Obviously I like them enough to make sure I always have them with me for work! ... show more
