This set of five brushes will ease your way into decorating your baked treats with scenes and designs that range from indistinct to intricate. The bristles are synthetic but soft, and safe to use on any food. The five different sizes are each made for different effects: Liner: wick-thin brush for drawing details Round: thicker than the liner brush, for wide or thin lines Small flat: the smallest of the three flat brushes, for shades of color or blends of color, or for embroidered designs Angled flat: brush with gradual increase in bristle length, for strokes that curve Large flat: brush for wide stripes Before your first use and after each subsequent one, wash by hand with warm water and non-harsh-chemicals soap. Press out excess water. Air dry.
