Princeton Summit is more than a new brush, it is next-generation technology. Princeton Summit Series 6850 White Synthetic Brushes were designed specifically for fluid acrylics but are also ideal for use with watercolors. Their unique blend of white synthetic filaments hold as much color as the best natural hair, they release color at a consistent rate, and they possess excellent points and edges. The NextGen synthetic filament in Princeton Summit brushes was developed by Naohide Takamoto, a fifth-generation brushmaker and the grandson of the inventor of Taklon, the first artist-grade synthetic brush fiber. Takamoto continues to dedicate himself to the development of synthetics that outperform their natural equivalents. After seven years of research and development, Princeton is proud to introduce Princeton Summit White Synthetic Brushes in a complete range of sizes and shapes.
