I use this ink for calligraphy, in a dip nib. Though one can make it very easily, who has time for that? The liquid comes all ready and it is one of my favorites to use, it keeps fine lines very well and shades quite naturally too. The sepia tone brings back a vintage look which cannot be replicated with regular ink. Pros: It is all natural! Great! Cons: It is all natural, therefore is prone to fading. I would keep artworks done with this ink well out of the sun.
