Huppy Mouthwash Tablets in Cool Mint are made from a blend of refreshing essential oils, fight bad breath while at-home or on-the-go and balance your mouth's pH levels. By reimagining mouthwash into a portable tablet, we’ve completely eliminated the need for plastic-packaging that contains harsh ingredients and mostly water. To use, chew a tablet until it dissolves, take a sip of water and swirl for thirty seconds, spit it out and take a deep, minty breath. Naturally blue color comes from Blue Spirulina Extract.
