OPEN Acrylics feature uniquely relaxed working characteristics and a remarkable ability to resist skinning and remain wet on the palette during long painting sessions. Working time varies according to how thickly the material is applied. Thin applications “tack up,” allowing additional layers to be applied and blended. Thicker applications may be worked for hours.
OPEN Acrylic Introductory Sets contain six 22 ml tubes packaged in a plastic case with an OPEN Application Guide.
