I recommend Garglin.

I recommend Gibun Gargrin as a basic oral care product.

It isn't too strong, and a subtle mint scent lingers after use, keeping your mouth fresh for a long time.

It comes in a small container, so I always keep it in my bag when I go out and use it whenever my mouth feels dry or unpleasant. If anyone is worried about bad breath, you should definitely try this mouthwash. It's so good!
