The two food-safe brushes in the set contain soft, synthetic bristles and are shaped to be used with Wilton Color Dust edible accents and Pearl Dust edible accents. Use the large brush to cover large areas of a fondant cake or to brush entire flowers with Color Dust edible accents or Pearl Dust edible accents. Use the small brush to dust small details on fondant or gum paste decorations, adding realistic shading to your designs.
