13 bags of Japanese painting doroe (mud pigments). These are not iwa-enogu (mineral pigments). These are partially used. They have been stored at home for about 30 years. There are about 350 grams in total for the 13 bags. This is the weight including the bags. Please forgive my amateur measurement. I'm sorry, but I don't know the details. Please consider this item as a used, long-term storage item.
