Sennelier Oil Sticks are made from pure concentrated pigment, the finest safflower oil, and high quality mineral wax. They're essentially traditional oil paint compressed into a convenient stick form that you can draw and paint with directly.These versatile art tools work like crayons but with the rich quality of oil paint. They can be used alone or in combination with tube oil paints and can be diluted with turpentine and dry to a hard film just like regular oils. You can apply them to canvas, canvas boards, laminated panels or paper, and layers can be overlapped. The sticks offer artists more freedom and flexibility than traditional tube paints - you can draw directly with them, blend colors on the surface, or create textured effects. These creamy, very lightfast sticks are perfect for both detailed work and broad color application, making oil painting more immediate and expressive.
