Princeton Dakota 6300 Series are an unbelievably versatile brush range they are perfect, not only for acrylics, but for traditional & water mixable oil colours .These long handled brushes feature the very first synthetic interlocking, inward curved hair that perfectly matches the stiffness of bristle, but with the resiliency and shape only a synthetic can give you. Easily power through the heaviest acrylics and make the most delicate line strokes with thinned colours too! A key advantage of 6300 is that it won’t go limp even in 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.
