Our journey to share healthy living with others has started! The stainless steel bottles are in! We have been using our bottles for a few months and LOVE them! The water tastes so pure. No dioxins or Bishphenol-A - a potent hormone disruptor found to leach from hard, plastic (particularly #7 polycarbonate plastic). The lids are from Polycarbonate #5, for safety reasons, you want to use #2 or #5, they are believed to be non toxic as the were not created using chlorine and do no contain the fore mentioned nasties.
