Tired of your acrylic paints drying too quickly? Explore Interactive’s Unique Formulation! Unlike traditional acrylics, all 75 of these “interactive” colors do not suddenly form a skin. Interactive changes the painting process, giving you plenty of time to blend and rework and giving you more creative freedom. The patent-pending formulation allows even touch-dry paint to be reworked or ragged-off to blend or reveal layers. Archival quality and lightfast, the intense colors dry to a satin-like finish without a plastic look or feel and minimal color shift.
