These are Yu-sai mineral pigments, no longer in production. ● Thick color, Hanakon (dark navy blue), No. 13, 15g ● Thin color, Konjo (navy blue), No. 11, 15g I have a large stock of Yu-sai blue pigments, and these were found in the new products section while I was organizing my paints. I believe this is the last unopened set. Please check the photos for the colors and numbers. The outer bags show some deterioration due to age. Thank you for your understanding.
