Wolff's Carbon Pencils
Included in the Carbon pencil set are four pencils in different degrees of hardness, 1 pencil in B, 1 pencil in 2B, 1 pencil in 4B and 1 pencil in 6B. Carbon pencils combine the properties of both graphite and charcoal together in pencil form.
Carbon pencils are ideal for drawing and sketching with bold, deep black lines, great for smudging, blending and shading. The perfect pencil for artists of any ability.
