HIGH FLOW ACRYLICS are an ultra-thin paint with ink-like consistency that provide incredible versatility. They can go directly from bottle to airbrush, refillable marker or dip pen and work great for drawing, staining, dripping, pouring, calligraphy and color washes.
High Flow offers a palette that includes many single-pigment colors, as well as Fluorescent and Iridescent colors. While it acts like an ink, it’s an acrylic so it's compatible with other GOLDEN Acrylic colors and mediums.
