Royal SableTek™ brushes are engineered to retain shape, sharp points and crisp edges over time, allowing the artist to lay down optimum amounts of color with precision and ease. These brushes are constructed of premium quality, multi-diameter synthetic filaments. A percentage of filaments used have a unique "wavy" profile, giving the brush exceptional color carrying capacity. Ideal for use with acrylics and oils, these brushes mimic natural mongoose hair in control and response. Close-work artists and decorative painters prefer these brushes due to their precise control.
