The Full Blender - Bright drawing tool is a colorless oil/wax medium for blending, dry mixing and intensifying colors. This single tool combines the mixing and unifying properties of a blender with a burnisher that consolidates and adds gloss. When applied over colored pencils or watercolor pencils, the pigments become even more lightfast and watercolor pencils become permanent (water-resistant). It has a hexagonal shape with a natural finish and woodless design. It's economical to use even on large projects, because 100% of the blender is available for use. It is a unique artists medium that opens up infinite technical possibilities and is ideal for use with Caran d'Ache colored pencils, graphite and wax pastels.
