Derwent’s waterbrushes with 3 head shapes have been exclusively developed for artists to paint ‘en plein air’. Easy to control water flow with a non drip valve, these brushes are portable, leak proof and easy to clean. Fine, Medium and Chisel tip heads are easily distinguished by number, so you can grab the one you need to paint with. The innovative Chisel tip gives firm, sharp fine lines or broad strokes when used side on. Paint outdoors with no water pot, no spills with these portable, refillable brushes.
