Watercolour pencils

You draw with a watercolour pencil just like an ordinary coloured pencil, and a pass with a wet brush turns the line into watercolour. Faber-Castell A.Dürer and A.Dürer Magnus are sold singly by shade number, so you can top up a set with exactly the colour that is missing. Goldfaber Aqua Creative Studio sets hold 12, 36 or 48 colours. Also available: Finenolo 24 colours in a metal tin, deVENTE 18 colours, Keyroad and Deli.
