Review: Very good pen. The writing quality is excellent - Very good pen. The writing quality is excellent. The nib is slightly thicker than I expected (it seems a bit thicker than my waterman M nib) but writes very well. The cap can't stay on the back of the pen as described, which does not bother me though since it is heavy enough for me and balanced without the cap.
Review: This pen has made my life so much easier... - It holds a lot of ink, writes smoothly and has enough weight so that you can write for long periods of time comfortably. I take notes a lot and it's not failed me once in the 12 months I've had it

### ⭐⭐⭐⭐⭐ Very good pen. The writing quality is excellent
*by T***T on 23 January 2018*

Very good pen. The writing quality is excellent. The nib is slightly thicker than I expected (it seems a bit thicker than my waterman M nib) but writes very well. The cap can't stay on the back of the pen as described, which does not bother me though since it is heavy enough for me and balanced without the cap.

### ⭐⭐⭐⭐⭐ This pen has made my life so much easier...
*by K***S on 25 October 2020*

It holds a lot of ink, writes smoothly and has enough weight so that you can write for long periods of time comfortably. I take notes a lot and it's not failed me once in the 12 months I've had it

### ⭐⭐⭐⭐⭐ Great for extended writing.
*by J***N on 15 May 2018*

Literally use this for everything. If you're going to be writing for hours at a time (I do for my 4 hour long essay-based exams) then this pen just floats across the page with ease and stops my hand from cramping up. Nib is fantastic.
