Water Brush Pen SET - DERWENT Set of 3 Fine, Medium & Flat
Portable, waterbrush pens with soft synthetic fibre tips, easy to use and great alongside any water-soluble media, perfect for taking out into the field, removing the need for water pots.
This set 1 each contains fine, medium point and chisel/flat tip brush.
The brush pens feature a patented valve designed to stop water from leaking when not required, but gives a constant flow of water when the brush meets paper, fed from the water in a refillable reservoir housed in the handle.
For wet on wet techniques just add slight pressure to the barrel.
To clean it simply apply pressure to the barrel and the dirty water will work its way out of the brush, wipe on a cloth or paper towel too.
