Derwent Colored Pencils, WaterColour, Water Color Pencils, Drawing, Art, Metal Tin, 12 Count (32881) STURDY PRECISION  Easy to sharpen, break-resistant pencils are ideal for long periods of use. With a 3.4mm core and hexagonal barrel, you gain precision for detailed drawings. Includes 12 colours. WATER SOLUBLE  Combine the control of a pencil with the beauty of watercolour. Use a wetted pencil tip to create rich textured lines or use dampened paper to obtain bright colours with soft edges. COLOUR LAYERING  Pigment transfers to paper quickly due to a softer formulation. This helps with blending and layering, creating a range of effects from bold colours to delicate watercolour washes. ARTISTIC FLEXIBILITY  Customize colours by adding water to create muted watercolour washes. As the pigment is not permanent, you can use water to move and adjust colours, even after it has dried. ACCESSORIES  For best results, combine with other Derwent products, such as Derwent Canvas Pencil Wrap, Derwent Waterbrush Set, Derwent Technique Brushes and Derwent Watercolour Paper Pads.
