Aquatone is a solid stick of watersoluble colour pigment in an easy to peel paper wrap. It has four times more useable material than our standard watercolour pencil. 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. Available in 24 vibrant colours Aquatone can be used with Derwent Watercolour pencils or other non-soluble Derwent media to add depth and interest.
