The Pro Arte Miniature Painting brush uses a stiff synthetic hair perfect for fine detailed painting in acrylic or oil paints. The firm hair keeps a sharp point while retailing a spring and responsiveness needed for painting in fine details. This makes this synthetic brush great for characteristics such as fine hairs, furs, eyelashes as well as natural features like grasses, leaves and trees. A triangular grip handle is used to all you to paint comfortably closer to the artwork, allowing for more precise strokes.
