I've been looking for the right aluminum water bottle ever since the whole, "Don't drink out of plastic bottles! You'll get cancer!" story came out. (I still use a BPA-free bottle at work, but I wanted a smaller metal bottle that would be handy to carry around and travel with.) I looked at REI, but most of the bottles were way too expensive and the ones that cost less made a terrible nails-on-chalkboard sound when I unscrewed the cap.
And then, at the Starbucks in my office building, I found it! It's cute. It's the right size. It wasn't too expensive. Perfect.
