Holbein Acrylic Ink - Ultramarine Blue, 30 ml

Offering the same pigment strength as Holbein Heavy Body Acrylics and Fluid Acrylics, Holbein Acrylic Ink has a much lower viscosity. Use it to create bold, brilliant color with a brush, airbrush, dip pen, technical, or refillable marker, and It will not clog a 0.1 mm aperture. It can also be used to achieve the subtle characteristics, washes, and tones of watercolor painting. Holbein Acrylic Ink is compatible with all Holbein watersoluble media. Conforms to ASTM D-4236. Note — Pearl White, Pearl Gold, and Pearl Silver Holbein Acrylic Inks will not flow properly through Holbein Refillable Markers, technical pens, or airbrushes due to their high mica content.
