Caran d\'Ache blue Technalo is a high-quality, water-soluble graphite pencil tinted with watercolour pigment. A medium-soft graphite lead, these pencils have excellent blending abilities whether used dry or wet. When used dry, the colour is only a subtle hint, mixed in with the natural dark tone of graphite. When wet, the watercolour pigment is intensified to bring rich tones of colour to your work. Technalo pencils can be used as they are, or applied with brushes when wet. - Brand: Caran d\'Ache - Colour: Prussian Blue - Water-soluble - Medium-soft graphite - Lightfast
