Developed in collaboration with Pablo Picasso in the 1940's, Sennelier Oil Pastels boast a creamy, lipstick-like texture and high levels of pigment for superb coverage, opacity, and lightfastness. These professional-grade pastels can be thinned with turpentine and applied to any surface with a brush. They are crafted using premium pigments, a pure synthetic binding medium, and mineral wax for long-lasting quality. The pigments are carefully ground with a non-siccative binding medium to prevent oxidation and ensure film and surface stability. The result is a smooth and creamy texture, perfect for creating bold strokes and expressing your creativity.
