Good ink for the right pen
This is my first Waterman ink. I thought it might be a little darker than it is, but monitors vary, etc.
It's a nice light blue, shading a bit toward turquoise. I originally had it in my Esterbrook Estie, but every time I wrote something, I kept thinking "This pen needs a darker ink." (Wholly subjective, YMMV.) So I ended up putting this ink in one of my Pilot Metropolitans, and put a darker ink in the Estie. Both pens were improved by the swap!
