Listerine Cool Mint, the pinnacle of oral care

It is Listerine, also known as the pinnacle of mouthwash.

You should gargle twice a day with 20 milliliters for about 30 seconds each time.

It is effective for removing bad breath and preventing and reducing plaque and gingivitis.

Compared to the commonly used mouthwash, Listerine feels really powerful(?) haha.

Still, it feels incredibly refreshing after doing it, so I feel like I'm getting addicted.
