### ⭐⭐⭐⭐⭐ Very comfortable to write with.
*by W***R on 19 December 2025*

Writes very comfortably. I’m not a connoisseur, but you can feel the difference between a pen that writes comfortably and one that doesn’t - this is a very good pen. I’ll get it again. (To Amazon: that’s not an invitation to drown me in ads)
