17 bags of Japanese painting pigments. These are partially used. They have been stored at home for about 30 years. Since they are partially used, the gram amounts written on the bags are not accurate. The total weight of the 17 bags, including the bags themselves, is about 230 grams. The weight of the bags is not subtracted. This is an amateur measurement. Please forgive me. I am sorry, but I do not know the details such as whether they are natural or artificial pigments. Please consider this item as a used, long-term stored item.
