This set consists of 12 polyester brushes. They can absorb a lot of water, which makes them suitable for highly thinned paints such as watercolours and inks. The set contains brushes in various shapes, each resulting in different effects or brush strokes. Due to the strength and resiliency of polyester, filament brushes are highly suited for oil and acrylic colours. As the filament brush absorbs water well, it is also suited for watercolour and gouache.
