This Water Brush from Faber Castell may be used in combination with watercolour pencils. It is ideal for wet-on-wet, glazing, and dry brushing techniques. This brush is also practical for mobile “on-the-go” use, such as urban sketching. The brush hairs made from high-quality nylon thread. Medium brush size. Watercolour pencil paint can be collected directly from the lead of the coloured pencil using this brush. By gentle application of pressure on the handle, water will run down to the tip.
