I purchased these at the Sennelier flagship store in Paris about 15 years ago. They haven't been used, but they are slightly deformed from transport. The stains are from other paints. They were stored in a can in a dark place. (There might be a tube or two where the cap was opened to check the color.) As you can see on Amazon, Sennelier paints are very expensive depending on the color. Because they are old, I'm selling them together at a low price. Quinacridone Purple Phthalo Blue Ultramarine Light Cadmium Yellow Deep Hue Chromium Oxide Green Burnt Umber These are six 34ml tubes. The tubes are not hardened at all. I think they are in good condition. Some caps might open easily, while others might be difficult to open. Although they are old, they are good paints, so I hope they will be used by experienced artists.
