1 Litre Water

I'm one of those annoying people who will complain about the taste of water, and yes it does make a difference if comes from the tap, the office cooler, or if it's bottled. 

So this product combines awesome design with great water (at an exceptionally high price, one would guess). It has been awarded with the “People’s Choice in Packaging and Design at the Berkeley Spring Water Tasting Competition
