The carbon pencil is the perfect combination of charcoal and
graphite. It has a fine grain, and goes on smoothly and precisely in
rich, velvety, matte black lines. Carbon pencils have a consistent
softness, for superior blending and texture.
The 5 mm core is encased within a natural cedar wood barrel, making
the pencils easy to use, and easy to sharpen for detail work. They are
available in four degrees of hardness — B (hardest), 2B, 4B, or 6B
