Why buy my product? Say you're planning a trip to one of these cities. You drink my product well before your trip, then enjoy your case of Montezuma's Revenge in the comfort of your own home, with easy access to familiar toilets and your family doctor. Then, when you get to your destination, you can enjoy the water and the street food with impunity!
Or maybe you're just bored with water that has no true taste or adventure!
