Derwent Aquatone Prussian Blue

A solid stick of watercolour in a peelable wrap. This versatile tool can be used in so many ways to create stunningly different drawing and paint effects. Use it wet or dry as a conventional pencil, as a block of solid colour or break it into convenient, easy to handle chunks. Can be used with Derwent watercolour pencils or other non-soluble Derwent media to add depth and interest.
