whats your opinion about this ink ??? if any of you could upload a scan it would be great
if i want a rich blue wich one is better MB o waterman??
thanks

I use both. Both are very good, but I prefer Waterman Florida Blue. If want you're looking is a truly awesome blue, try mixing 1:1 parts of Florida Blue and Violet. Incredible color, unbeatable ink qualities.

If you need to see the colors I suggest you use the search function, there are a few reviews already.

the violet is from waterman too ??? i´ll try to get it and see how it works . about the samples i couldn´t find de MB

For years I avoided MB ink of all flavors because "everyone" said it was an inferior, whimpy ink. After using PR and then Noodler's, and finding that I spent more time cleaning pens than using them, I started looking for inks that I could just write with, without having to do pen overhauls every other week. Diamine and Waterman are the two biggest candidates, but I really don't care much for Floriida Blue (Waterman), and Waterman Blue-Black isn't really BB, is it? Therefore, MB Royal Blue has become my blue ink. Pelikan Royal Blue is just too washed out, even after the recent color adjustment.

Yes, Waterman Purple or Violet ( it has all names in French and English).
