Review on Convenient Listerine Ready! Tabs Whitening Chewable Tablets: Polar Mint Flavor to 🦷 Combat Bad Breath, Whiten Teeth, and Eliminate Germs Anywhere, 24 ct, Sugar-Free, Gluten-Free by Susanberry Berg

That's what you need in your pocket for shame. It freshens your breath. Gets the taste out of your mouth the nasty night before. They are small, travel and pack well. Also very discreet. It also frees the mouthwash from your 3-1-1 airline travel bag. It's high on my list. I even keep some in my purse in case I eat something strong for dinner. Easier than having a toothbrush and toothpaste in my purse.
