Gustave Sennelier opened this art supply store in 1887, near the famous Ecole des Beaux-Arts. He was anecdotally noted for manufacturing specialist colours and materials for Cézanne and Picasso. With some of the most luxurious materials available, Sennelier are ubiquitous with quality and performance. Their key ranges are their soft pastels, oil pastels and of course their L’Aquarelle watercolours.
