Do these water bottles keep the water cold or would it warm up being copper?

Hi Michelle
Copper is an excellent conductor and these bottles are made of pure copper (and nothing else) - so the water will cool down really fast in cold conditions and warm up in hotter conditions. They are not meant to work as a thermos / insulated flask but to alkalise and impart other benefits to the water stored inside.
