Nabi reimagines Korean pop lightsticks—LED devices fans wave at concerts to show support for their favorite artists—as a modular, emotionally resonant object with extended life beyond performances. Driven by fan sentiment and the environmental costs of constant merchandise turnover, the design introduces a customizable base, interchangeable group-specific tops, and a speaker-display system that lets fans relive concert memories at home. By prioritizing reusability, personalization, and memory preservation, the project offers a flexible alternative to traditional merch, helping fans celebrate their identity without unnecessary waste.
