A selection of 7 painting palette knives ideal for a wide variety of painting techniques, such as impasto, contained in a handy, protective zip case. Made for use with Daler-Rowney System3 Acrylic Paints. Daler-Rowney Palette Spatulas have a special electrolytic coating that is unique in the fine art market. This additional coating results in a product that is more resistant to rust than all other carbon steel palette knives (which until this innovation have been the industry standard).
