Grey Matters brushes are designed so that nothing stands between you and the canvas. Each Jack Richeson brush is carefully handcrafted so that you can do your best work. There are no distracting colors on the handles and the metal ferrules are non-reflective. This brush has synthetic hairs for acrylic painting and the handle is a neutral gray so you can focus on your artwork. Flat brushes hold a lot of color and lay down broad, sweeping strokes.
