A better, longer lasting bristle brush that cooperates better than natural bristle across a broad range of mediums. 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 mediums.
