Drink bottle, $3

It often strikes me as absurdly luxurious that drinking water comes out of virtually every tap in town. Whether you’re washing your hair at home or cooling the deck of a wok cooker in a restaurant kitchen, out comes the same crystal clear water. This drink bottle is small enough to slip inside a handbag and good-looking enough to pull out of one, and together with a little foresight and some public restroom derring-do, you may never need to buy bottled water again.
