Derwent Blender Pencil
If you want to create a subtle blend of colours then the Derwent Blender pencil is the ideal accessory. The Blender pencil is a soft colourless pencil made from the binder used for coloured pencils. It allows you to blend two or more colours together to create a new colour. At the same time it physically mixes and smoothes the colours so individual strokes and hard edges are softened.
