The Blender pencil is a soft colourless pencil that allows you to blend two or more colours together to create a new colour. At the same time it physically mixes and smooths the colours so individual strokes and hard edges are softened. The Derwent Burnisher is a hard colourless pencil which when used over layers of pigment provides a rich polished finish.
