Contains the essentials of the Sketch range: 1 XVIII Sanguine pencil, 1 Medici Sanguine pencil, 1 Black Stone 3B, 1 White, 1 Sanguine and 1 Sepia. The graduations go from H (Hard in English) for hardness to B (Bold in English) for softness. The higher the number, the harder or softer the pencil. The pencils can be sharpened with a knife or cutter. Perfect for quick sketches, nudes, portraits and landscapes. With a sharpened lead, the line is precise, the color is transparent if the work is lightly sketched. With a half-worn lead, the opacity increases, also depending on the pressure exerted.
