Derwent Waterbrushes have been specially created for artists who like to paint outdoors, and don’t want to be lugging lots of awkward equipment around. Each brush has its own reservoir of water, so you don’t need to fiddle about with water pots, giving you more time and energy to devote to your art. The non-drip valve makes it easy to control the flow of the water, and the brushes are leak-proof and easy to clean and refill. This set contains three Derwent Waterbrushes with lid, Fine, Medium and Chisel-tip heads.
