This handy Derwent Waterbrush is a water holder and brush, all in one. The brush houses water in the barrel of the pen which is supplied to the fibre brush via a valve, giving a constant flow of water when the brush meets paper.
For wet on wet techniques just add slight pressure to the barrel of the pen, and to clean it simply apply pressure to the barrel and the dirty water will work It's way out of the brush.
- Handy brush which also holds water
- Ideal for every watercolour artist
