Diamine Mediterranean Blue is a great shade of blue. I think it is a good and cheap alternative of Iroshizuku Ama-Iro.
Diamine Mediterranean Blue has a great shading especially when it is used with wet writers. Less shading acquired with drier pens. It is a shade of blue suitable for daily writing.
I tried this ink with my music nib Sailor 1911 fountain pen. Even though it is a bit dry for this pen, I did not have any problems. Nevertheless it is not a waterproof ink but it was washed away easily, quite problem-free like other Diamine inks.
