Winsor & Noewton's Galeria Series is specifically designed for use with acrylic color. The versatility of acrylic color can place heavy demands on brushes so this range has been created to be strong, resilient and flexible. The mix of synthetic filaments provide responsiveness and control for thicker application of paint, while maintaining shape retention, regardless of how much water you use. The synthetic filaments in the flat brushes are curved, helping to retain the original shape during use. The round brushes offer a good point for delicate linear application. The brushes with short-handles have a softer head, ideal for glazing or a water color style of painting. The long-handled brushes are made from stiffer filaments, allowing thicker application on tougher surfaces.
