This pen is my favourite of my four white capped M600s. I love the candy striped pattern of dark pink and clear.
An old M620 18K medium that writes finer than medium - this is not a bad thing!
Rohrer & Klingner Sepia is a true to colour sepia that is otherwise not that exciting. A little shading and no sheen whatsoever. This shade will go well at the office as a different work safe ink.
