First, thank you so much for this comprehensive introduction. Second, it should be noted that, in the U.S., Vanness is now carrying the Callifolio inks. (Yay!)
Yes, that you Vis for your excellent review of this line of inks. I really appreciate your swabs of Olivestre. I have found very few dark green colors that I like, but this has potential. I also like Inti, as well as Anahuac.
Inks by the mL (http://inkbytheml.squarespace.com/) carries 5mL samples of many of the Callifolio line. I am awaiting my order for the samples now. As soon as I give them a test run, I will probably make a substantial order with Vanness.
