This set of 3 polyester brushes can absorb a lot of water, which makes it suitable for highly thinned paints such as watercolours and inks. The set contains the following types and sizes: 2 round brushes in sizes 6 and 8, flat liner brush in size 5/8”. 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 watercolour and gouache.
