Sennelier
Sennelier is a French brand of art supplies famous for their hand selected pigments. They produce oil paints, water colors, gouache, pastels, india ink and many other mediums.
Gustave Sennelier opened this art supply store in 1887, near the famous Ecole des Beaux-Arts. Initially, Sennelier sold paints made by various manufacturers; later he chose to produce his own paints using local pigments and binders procured from his travels across Europe.
