Holbein Artists' Watercolours are made in Japan. They are moist transparent watercolours of unsurpassed purity, permanence and brilliance in 15 ml tubes. They are available in 108 highly concentrated watercolours. Holbein Artist Watercolor is a European style transparent watercolour which preserves the brush handling qualities inherent in Japanese watercolour techniques.More finely ground than any other artist watercolour, Holbein Artist Watercolour is produced without ox-gall, animal by-products or other dispersing agents. This affords the user greater control in the dispersal of their pigments, enhances handling qualities and delivers colourΒ of unequaled intensity, purity and reliability for brilliant transparent washes and powerful, clean darks.
