Pro-Art Brush Sets are comprised of artist’s quality Brown Taklon brushes. With this type of Taklon being on the softer side of synthetic hairs, yet still durable, these brushes are ideal for Watercolour! Mimicking natural hairs, the flexibility of Brown Taklon results in good water and pigment holding. Synthetic filament, being manmade, is also less prone to damage from solvents, bugs, or paint.
