Quality Pigments guarantee Brilliant Lasting Results! Holbein Artists’ Oil Pastels are soft, creamy, and fun to use. Endorsed by the Oil Pastel Association of America (OPA), Holbein Artists’ Oil Pastels move and feel like creamy chalk pastels minus the dust. The color lays down cleanly and evenly without stickiness. You can mix the rich colors dry or with linseed oil. They guarantee color consistency by tracking pigment distribution and purity. The colors never completely dry out because Holbein suspends the pigments in a mixture of wax and mineral oil. These pastels provide brilliant results on paper and canvas. The large square stick shape is easy to hold and less prone to breakage. The set includes 40 assorted colors.
