The Prismacolor Colorless Blender uses a special formula to soften hard edges, and to lighten or blend colored pencils. Use it for a smooth, blended look. With the Colorless Blender, colors can be layered on top of each other without cloudy build up. This pencil is sold unsharpened.
Note — Manual sharpening is recommended for this pencil. Clogging can be prevented in electric sharpeners by periodically sharpening a graphite pencil to keep the blades clean.
