An excellent pen. I prefer the svelte design of the CP1 over some of the overly
bulky fountain pens produced by other manufacturers. I replaced the stock silver
color nib with a Lamy black fine nib to give it a more cohesive aesthetic. The
pen feels exceptionally high quality and looks very professional. My only gripe
is that it can write a little dry depending on what inks are used. For example,
I had an issue using Lamy blue-black in this pen. However, I have found that
Diamine and J Herbin inks work exceptionally well. I have been so impressed with
this pen that I use it exclusively as my EDC.
Tested this ink in a Lamy CP1 with a fine nib. This ink is definitely on the dry
side and my pen has a hard time maintaining sufficient ink flow. As another user
noted, the ink looks great (nice and saturated dark blue with good shading) for
the first few words of a sentence; however, upon further writing the ink
subsequently writes much lighter and dries to a steel-blue color. This ink would
be good in a wetter writing pen. I am now using Diamine Blue-Black and am very
satisfied with the performance of that ink when compared to the Lamy Blue-Black.
