This Derwent Watercolour Pencils offer the control of a pencil and the beauty of watercolour. Mix with water to create interesting colour flows and stunning watercolour effects. These professional-quality, water-soluble pencils offer the artist the freedom to switch from drawing to painting in an instant. Use them to shade on dry paper, then wash over with brush and water to get a blending effect. Use on wet paper for intensified colours with softened edges, or wet the pencil for rich, textured lines. Each pencil is pre-sharpened and has a 3.4mm diameter colour strip.
