All Derwent Sketching Pencils are rated 8 on the Blue Wool Lightfastness Scale. All three grades of pencil contain animal fat in the wax blend.
A wonderful choice for free style sketches and bold line drawings, allowing complete and spontaneous freedom of expression. The soft, extra wide graphite strip sweeps smoothly across the paper for a fast, even lay down of tone but is equally suitable for more detailed work. Derwent Sketching comes in three versatile degrees which blend together beautifully, creating subtle variations in tone and mood.
