At Cass Art, we are celebrating our 40th anniversary by expanding our Artists' Oil Paint range with 19 new colours! Our Artists' Oil Colours is an extra fine professional grade Oil colour produced with the highest possible level of pigmentation. Their rich, buttery consistency is achieved through the use of a triple-milled unique and natural formula. Compared with most Artists' Oil ranges the colours offer a slightly shorter drying time which is more consistent across all of the colours.
