Made from refined linseed oil blended with a quality pigment and solidified into a convenient stick form for a rich, creamy, buttery consistency. Ideal for sketching, outlining, or covering large areas and colors are mixable. Can be spread or blended and used in conjunction with conventional oil paint. No unpleasant odors or fumes. Use to paint on almost any surface from paper to panel to fabric as most colors dry within 24 hours. Painting are self-sealing; they form a protective film so color won't rub off or dry out, yet they always stay moist and fresh for an indefinite shelf life. These oil paint sticks can be used with traditional oil paint techniques, mediums, Varnishes, and surfaces. Non-toxic and hypo-allergenic. Blistercarded.
