Use over colour to create an impressive shine. 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 very well blended, photo like finish. It makes the colours look brighter and can give an image a polished or reflective look by sealing it with a heavy layer of colourless wax. The Derwent Burnisher is available individually or as part of the Burnisher & Blender Set. Specifications..
