I have new large tubes of Rembrant (20ml) that I won in an art contest. They are colors that I don’t use. The colors are; Ivory Black, Chinese white, Hooker Green deep, Yellow Ochre, Prussian blue and slightly used Alizarin Crimson. I am willing to sell or trade. These paints retail for between $16.95 and $24.95 each tube (depending upon the series) . I would be happy to sell or trade them. I live in the US.
