4-pcs Pull Wire Paint Brush Gouache Nylon Hair Knife-shaped Watercolor Pen Set Water Painting Pen Hand-painted Art Drawing Brush

I expected something completely different from the brushes. There is practically no springiness to the bristles. While the two thin brushes (8 and 12) can still be used somehow in watercolor, the two thick ones (16 and 20) were a complete disappointment: they don't gather into a single point, and moreover, they bend. It looks very much like the brushes might only be suitable for calligraphy.
