With over a century of experience and a reputation to match, Sennelier is a brand name every artist should know. Originally created in the 1940's as a collaboration between Henri Sennelier and Pablo Picasso, Sennelier's oil pastels are not only famous for the aforementioned names, they are known for being rich in pigment, covering surfaces well, and their outstanding opacity and lightfastness. The pastels in Sennelier's Plein Air Oil Pastel Wood Box Set of 36 are made of top-quality pigments, an extremely pure synthetic binding medium, and mineral wax. Chosen by award-winning artists, this acid-free pastel set has a range with more darks, greys, blues, greens and earth tones. Ideal for artists on the go, the Sennelier Plein Air Oil Pastel Wood Box Set is perfect for travel in the secure and compact foam-lined wood box. Best of all, the creamy oil pastels can be used by the pastel artist or oil painter and can be given as a gift to friends and family, or as a gift to yourself!
