Conté Pierre Noire pencils are made with soft leads that are dense, deep, indelible and matt black. These pencils work brilliantly on all types of supports, from craft paper to linen canvas.  These pencils are suited to both drawing and sketching. With a sharpened lead, the drawing is lively and accurate; with a half-worn lead, the work is more spontaneous and free. Available in different degrees of hardness ranging from H to 3B.  Length 176.5mm / Diameter 8.5mm / Lead diameter 5mm. Download the information chart here (PDF)
