Derwent Onyx Pencils Singles - DARK GRAPHITE - MEDIUM & DARK

Onyx is Derwent's blackest graphite pencil, even darker than a 9B, available in two tones- medium and dark

Use on its own for drawing really intensely dark pictures or use it with other graphite media like Graphic or Sketching pencils to add dense tone and shade.

It is easy to build up darker shades if you need them by increasing the pressure.

The wide strip can be easily sharpened and will hold a fine point, perfect for creating the detail in drawings.
