The distinctly patterned M620 San Francisco makes its 15th time in rotation since I bought it some 5¾ years ago. It is still one of my favourite pens just to gaze at.
At seven years, four months this nib has spend the second longest time in my collection, clocking up 16 times in rotation. It is a nice wet medium nib that just writes well.
I love Montblanc Irish Green - it is a lovely emerald green that shades and exhibits a red sheen on occasion. This particular ink has been in collection for over seven years.
