Princeton's flagship brush. Almost 20 years ago, series 4050 was the first synthetic sable to be offered to artists. This brush has been copied many times, but never equaled. A perfect blend of multiple diameters of golden taklon hair, this brush was developed for Princeton by master Japanese brush-maker Naohide Takamoto, the "Tak" in "taklon." This brush drinks up gulps of water, paints out in supple strokes with a natural snap. Paint, scrub, and push knowing that 4050 will always return to a tight point or crisp edge.
