Understanding the Appeal of Muji Aluminium Fountain Pens
I’ve always appreciated the minimalist design philosophy of Muji, and their aluminium fountain pen is no exception.

Comfort during writing is essential. I evaluated the pen’s weight distribution and grip section to ensure it felt balanced in my hand. The aluminium body can sometimes feel cold or slippery, so I paid attention to how the pen performed during longer writing sessions. I also considered the pen’s size and diameter to make sure it suited my grip style.
Portability and Design Aesthetics
Given the pen’s aluminium construction, I found it to be sturdy enough for everyday carry without worrying about damage. Its minimalist design fits well in professional or casual settings. I also thought about how the pen’s clip (if included) would secure it in my pocket or notebook.
Price and Value for Money
