These watercolour pencils provide artists' with great versatility of expression when drawing, shading and painting in watercolours. High quality materials combined with Faber Castell's experience have resulted in pencils that produce unsurpassed watercolour effects. The coloured surface can be transformed with only a few fine or broad brushstrokes to reveal the full and unique power of the colours. Depending on the paper being used, the pigments can be completely dissolved, and will then behave in the same way as classic watercolour paints. The paint becomes permanent when dry, enabling other layers of colour to be superimposmed without causing it to dissolve again. For this reason, many watercolour artists choose to use the pencils for fine details in their watercolour paintings, as well as for watercolour sketches while travelling.
