Vai Vai water
Models, foodies, health freaks love it. I am none of the previous and I love it.
I love the subtle fruity taste, the fact it contains next to no calories per drink, its loaded with Potassium and hydrates your skin and the rest of you, from the inside. It really quenches my thirst and I feel it makes my skin look better, yes, promise.
You can buy it online as it cheaper and they deliver anywhere you want.
I always have a carton in my bag, just in case.
