These 12 polyester brushes can absorb a lot of water, which makes it suitable for highly thinned paints such as water colours and inks. The set contains brushes in various shapes, each resulting in different effects or brush strokes. Filament brushes consist of synthetic fibres (polyester) and are suitable for all types of paint. Due to the strength and resiliency of polyester, filament brushes are highly suited for oil and acrylic colours. As the filament brush absorbs moisture well, it is also suited for water colour and gouache.
