This set consists of 5 brushes made with pony hair and polyester filament. They can absorb a lot of water, which makes them suitable for highly thinned paints such as watercolours and inks. This set contains the following types and sizes: 3 round brushes in sizes 6, 10 and 14, 2 flat brushes in sizes 8 and 14. Due to the strength and resiliency of polyester, filament brushes are highly suited for oil and acrylic colours. As the pony hair is a soft type of hair that absorbs water well, the brush is also suited for watercolour and gouache.
