Whilst these Revolution brushes are made from Taklon bristles, new technology allows them to carefully replicate the natural scaling in animal hair by creating microscopic pock marks on the surface of the fibre, replicating the scaling of natural hair. This gives them a better holding capacity and smoother, even release than other synthetic alternatives. These brushes behave like sable brushes with the advantage of better fibre elasticity for superior spring and recovery. This means they are more resilient and hold their shape for longer than natural filaments. The synthetic filaments are also slightly stiffer than sable hair, enabling sharper points and edges in these brushes. Ideal for watercolour. Also suitable for some oil, acrylic and gouache techniques (great for glazing and thin application, not suitable for heavy body paint). The nickel-plated ferrules on the brushes resist corrosion from paint and water. This size # 10 is ideal for medium application and confident strokes.
