Skisspennor.

Sepia Pencil - this gives a colour reminiscent of burnt umber. It shades easily and when sharp gives an accurate and delicate finish. With a half-worn lead, the finish becomes more opaque as the pressure exerted on the pencil increases

Sanguine Pencil - The colour of the Conté à Paris "Sanguine" pencil is a deep "rust" and its lines are easily blended.

White Pencil - best used with a sharp lead, this pencil gives a clear line with a transparent colour.
