In 1949 Sennelier started developing a range of artists' quality pastels for the famous artist Pablo Picasso. Picasso was looking for a pastel with intense colour that could be applied directly and freely to a wide variety of surfaces. As a result Sennelier created an oil pastel with a soft creamy quality with all the intensity and vibrancy of conventional oil colours. However, unlike oil colours, Sennelier oil pastels are made using a unique combination of non-aggressive oils and waxes so that they can be used on almost any surface, including paper, without cracking or affecting the substrate. All 120 colours in the full range are 100% lightfast making the Sennelier oil pastel range probably the only true artists' quality oil pastel in the world. Box of 24 assorted oil pastels.
