Iwa-enogu (mineral pigments): I've gathered silver gray, ultramarine, navy, and purple shades. There's just under 200g of iwa-enogu in total. Please refer to the photos for the capacity and colors. This belonged to my grandmother, who used to study Nihonga (Japanese-style painting), so I don't have detailed knowledge and cannot answer specific questions. I've replaced the bags that were deteriorating with new ones and relabeled them. Some are still old. There might be discrepancies between the labels and the contents, but I don't have the expertise to know. Please make your judgment based on the photos. I'm selling these at a low price, so please refrain from purchasing if you are concerned about minor details. I apologize that the colors may not be accurately represented due to the lighting in the photos.
