This set of 3 polyester brushes can absorb a lot of water, making it suitable for highly diluted paints such as watercolours and inks. The set contains the following types and sizes of brushes: 3 round brushes in sizes 4, 6 and 8. The filament brushes are made of synthetic fibres (polyester) and are suitable for all types of paint. Thanks to the strength and elasticity of polyester, these brushes are ideal for oil and acrylic paints. But thanks to their high absorbency, they are also suitable for watercolours and gouache.
