Liquitex wants us to “Re-Think INK” with its line of Professional Acrylic Inks designed with the artist in mind. The 30 intense, bold colors are packaged in 30 ml. glass dropper bottles and are extremely fluid–no need to dilute for air brushing or calligraphy. They are fast drying, water resistant, non-clogging and permanent and intermixable with all other Liquitex Acrylics and Mediums. The 10 best selling colors in the line are also available in a 150 ml. bottle.
