Derwent
Blender and Burnisher

Burnisher
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.

Blender
If you want to create a subtle blend of colours then the Derwent Blender is the ideal accessory. It allows you to blend two or more colour 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.
