If you’re used to vapor, Lio might feel lighter at first—but it’s designed for a healthier future. Think of Lio as herbal tea compared to the sticky soda of vapor: less intense, more natural, and far better for you.

Each Lio Core lasts 2-4 days, depending on your usage. Heavy users may need to replace the cores more frequently, but they are designed to provide lasting flavor and a satisfying experience.
