Based on the prototype of the retro rectangular license plate, the blue "champion" letters and the red details are presented through enamel painting technique, preserving the retro color on the metal surface. The front maintains a clear identification language, while the back ends with a metallic texture embossing, enhancing the contrast between color and texture, making the earrings both recognizable and suitable for daily wear.
