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 colours, rich and vivid tones. At the same time it physically mixes and smoothes 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. Burnishing pushes the pigment into the paper and leaves a well blended, photo like finish. By sealing the image with a heavy layer of colourless wax it gives the image a polished or reflective look and makes the colours appear brighter. 

Derwent Blender & Burnisher sets are versatile tools for subtle or intense color pencil effects.  They may be used individually or together. The Blender & Burnisher Set includes two of each style plus a sharpener and an eraser.
