Holbein 15ml Artist Watercolour W307 - Phthalo Blue Yellow Shade

More finely ground than any other artist watercolor, Holbein Artist Watercolor is produced without ox-gall, an animal by-product. This affords the user greater control in the dispersal of their pigments, enhances handling qualities and delivers color of unequaled intensity, purity and reliability for brilliant transparent washes and/or powerful, clean darks.
