The City of Lights also has a reputation as being a city of art, and for over 100 years, Magasin Sennelier has been supplying those artists with the tools they need. Still owned by the Sennelier family, the store has served names like Cézanne, Degas, Picasso — his oil pastels are still best-sellers — and Lagerfeld, many times creating new products and shades to their exact specifications. Inside, you'll find literally hundreds of different shades of pastels, along with huge arrays of pens, pencils, and papers. Need some inspiration? Just head out the door and cross the river, where you'll find more than you'll need inside Le Louvre.
