Great for travel!
Color: Refreshing Mouthwash, Size: 0.41 Fl Oz (Pack of 30)
Best thing we have come across lately! Bought them for a 4 week trip. Easy to open. Good taste. There's a little peroxide n it, but it's not too foamy. Great for travel. Will be buying it regularly. My husband and I are both big fans.

Practical for the size but doesn't last
Color: Refreshing Mouthwash, Size: 0.41 Fl Oz (Pack of 30)
Good for travellers and easy to use. It doesn't take too much space in your bag, but it doesn't last long enough
