Ink is super fluid; highly pigmented, extremely fluid with satin finish. Pouring Medium creates even puddles, poured sheets and flowing applications of color. Both the ink and the pouring medium are lightweight, non-toxic and dry to a water-resistant, non-yellowing surface. Each ink is made with super-fine artist-grade pigments captured in cutting-edge acrylic emulsion. Contains three 1-oz/30ml containers of ink (Yellow Medium Azo, Quinacridone Magenta, and Phthalocyanine Blue (GS)) and one 4-oz/118ml Professional Pouring Medium.
