In terms of application, rainbow metal zippers are being integrated into a wide range of clothing items. They are commonly found on jackets, jeans, dresses, and skirts, where they serve both functional and decorative purposes. The zippers can be used as a focal point, drawing attention to the design and adding a pop of color to an otherwise neutral outfit. Additionally, they can be strategically placed to create visual interest, such as along the seams or as a central design element.
