A better, longer lasting bristle brush that performs better than natural bristle across a broad range of media. A key advantage of 6300 is that it won’t go limp in even water! Try that with natural bristle! Modeled on the look and feel of hog bristle, series 6300 is a perfect brush for painters switching from oils to acrylic or water miscible oil. A real workhorse in even heavy bodied acrylics and suitable for use with gels and impasto media. Oil painters are catching on to 6300, realizing that it wears much better than natural bristle.
