For the last 130 years, Sennelier has combined the innovations of modern chemistry with the traditions of the Old Masters to produce internationally regarded art materials used by Cezanne, Picasso, Bonnard and Soutine. Each medium solves major problems faced by artists: their artist oils are made with non-yellowing safflower oil, their oil pastels are some of the softest available, they produce the widest colour range of soft pastels, and their watercolour formula includes an exceptional ratio of honey to ensure radiance and luminosity.
