Both functional and aesthetically pleasing! ت

The Muji Cap Type Gel Ink Pen in 0.5 mm Black is an absolute writing dream come true! This pen has redefined my writing experience with its exceptional performance, sleek design, and reliable ink flow. The 0.5 mm tip size strikes the perfect balance between precision and smoothness. Whether I'm jotting down quick notes or engaging in more detailed writing tasks, the pen effortlessly glides across the page, leaving behind consistently dark and crisp lines. The black ink is of top-notch quality. It dries quickly to prevent smudging, which is especially handy for someone like me who tends to be a bit impatient. The ink is also consistently rich and vivid, adding a touch of elegance to my writing. The cap design not only protects the pen tip but also adds a touch of minimalistic sophistication.


The Muji Cap Type Gel Ink Pen in 0.5 mm black is a neat and professional writing instrument. The pen's smooth flow and precise 0.5 mm tip create clean and legible lines. The black ink is dark and bold, making my writing look professional and elegant. The cap type design is practical, preventing any accidental staining in my bag or pocket. However, I wish the pen had a clip for added convenience. Despite this, I've found the pen to be reliable and a great choice for everyday writing tasks. If you're in search of a no-nonsense gel pen with a consistent performance, this Muji pen is worth considering.

The cap type design is convenient, and the pen's cap clicks securely in place to prevent any accidental leakage.

My favorite pen!

This pen writes really smoothly, very nice, and overall makes your handwriting look very good. But the 4 stars are because if you use it a lotttttt you will run out of ink quickly. So if you think this is a nice pen, consider getting 3 or 2 of it.

Definitely would recommend! 👍

Gets all the little crevices on your paper or sticky notes, super great and durable never runs out of ink. I really like this so I could take my aesthetic note-taking and it was great in general! My shipping took 10 to 12 days to ship which is really fast for someone who lives in the United States. It came in the cutest Packaging and really is amazing! Definitely would recommend! :-)
