This set includes a Caran d'Ache Pencil Blender and a Full Blender. The Pencil Blender is designed to blend artwork created with colored pencils, softening shades and stroke lines, and can be sharpened with any standard pencil sharpener. The Full Blender is made from a colorless oil-wax mixture, ideal for blending and burnishing artwork across various mediums, including colored pencils, graphite lead, and wax pastels. These tools are perfect for both creative professionals and hobby artists to blend, mix, and intensify colors without altering their original hue.
