Okuchi Gachi Lemon is a convenient single-use stick mouthwash from Japan, containing 11ml per packet. This non-alcoholic, low-irritation formula features a refreshing lemon flavor and contains kitosan and tea leaf extract that binds with protein-based debris in your mouth. What makes it unique is that it visually shows the removed debris as brown particles after 20 seconds of gargling. Perfect for on-the-go oral care when brushing isn't possible, like at work, school, or while traveling.
