Koh-I-Noor Progresso woodless pencil, made entirely from a colored core and coated with a colorless lacquer. This makes it ideal for drawing outlines, filling large areas, and creating soft transitions between colors and shades. Additionally, the shavings produced during sharpening can be used for shading and filling drawing areas with color by rubbing them with a finger or a sanding tool. It can be sharpened with regular sharpeners. Set of 12 colors.
