The Liquitex Basics Set of 2 Large Flat Synthetic Brushes includes two brushes with broad, flat bristles. The sizes included in this set are 1 1/2" and 2". These large scale brushes are perfect for applying acrylic paint on big projects. They are also ideal for priming canvases, working on murals, laying down bulk colour for backgrounds and all acrylic painting techniques. Their natural bristles makes them great for manipulating thick paint, and also adds texture to your work as brush marks are left. To keep your brushes in good condition clean them thoroughly with water before the paint dries.
