Review on 🖌️ Kuretake ZIG CARTOONIST SUPER BLACK INK 60ml - Professional Quality for Dip Pen, Calligraphy, Lettering, Illustration, Drawing, Inking Art, Cartooning - Made in Japan (Super Black Ink) by Kristen Simpson

Great ink for work, very dark, dries quickly (which may or may not be professional depending on how you work), seems fairly waterproof, although I haven't been super difficult with watercolour . It dries fairly quickly and in a thick layer on the pen - not a big problem when drawing but make sure you have some alcohol or acetone to clean the pen afterwards as water doesn't help. The wide mouth of the bottle is a godsend for fountain pens, I never have to worry about ink spilling onto the body of the pen holder, which I didn't appreciate until I used it.
