Lightly tested, just a few brush strokes to try the colours. Bought a while ago; they’re honestly too beautiful to sell, but I’m going through a tough time and have to let them go. Some paints may have slightly separated, but a gentle stir will bring them back to normal. Mineral Violet has completely hardened; however, it can still be used as a solid watercolour if cut into smaller pieces. (I own five full sets, but this one is the only perfect one. Don’t hesitate if you’re collecting M. Graham.)
