Golden OPEN Acrylic is a slowdrying acrylic paint that enables painters to explore techniques traditionally reserved for oil paints. The slowdrying quality gives artists longer working time for easier blending and even subtractive techniques. There is a unique thinner and mediums for use with OPEN, but the paints are compatible with regular fastdrying acrylics and clean up with soap and water like regular acrylics.
