These shellac-based colored inks are mixed with natural pigments, resulting in a tremendous selection of high-quality colors. Sennelier Shellac Inks can be applied with either a brush or ink pen and give off a satin to brilliant film depending on thickness. Colors are blendable and can be reduced with a shellac-based thinner for various techniques. They dry very quickly and display a high degree of water resistance without being indelible. By fixing with an UV Spray fixative, Sennelier Ink's light stability is greatly increased.
