The Wilton Candy Melts Decorating Tip Set makes decorating easy! Three tips - drizzling tip, writing tip, ribbon tip - help you accomplish detailed decorating with ease. Just slip a coupler in a piping bag, cut the tip of the bag, twist the microwave cap onto the coupler, fill with Candy Melts candy and melt candy in the microwave. Once the candy is melted, replace the cap with the desired tip and decorate! Drizzling tip has three fine holes to quickly add a drizzled look to your treats. Writing tip is great for writing or making lines or dots, while the ribbon tip makes a wide, flat line of candy. All tips, coupler and cap are microwave safe.
