Raw Pigments are Acrylic-Free, Powder Based, Vegan, & Organic and have never been tested on animals. Artists really like how fast and solid Raw saturates. Colors are formulated to not dry out in your caps during long sessions and in the bottom of the bottles. Each share an even viscosity and mix well with other inks and brands. Consistency over time is the most important thing. Every bottle is a perfect match. Pigments are Made in the USA.
