Caran d\'Ache blue Grafcube is a high-quality, water-soluble graphite stick tinted with watercolour pigment. A medium-soft graphite lead, these sticks 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. Grafcubes can be used as they are, or applied with fingers or tools such as brushes. - Brand: Caran d\'Ache - Colour: Blue - Water-soluble - 10mm wide - Medium-soft graphite - Lightfast
