A major obstacle encountered during the development process was the selection and coordination of color schemes. In the proposal phase, we explored three main directions—trendy, luxurious, and professional—resulting in 16 different combinations, which were then narrowed down to five. Following user research, we picked white, pink, and blue.

And various components were sourced from different suppliers, including those employing dual-color injection molding, pad printing, and overmolding techniques. Therefore, we coordinated with multiple suppliers to ensure harmonious color combinations and supervised quality control throughout the process.
