PUNC Bottles are a range of Stainless Steel water bottles, they are made from 304 (18/8) food grade stainless steel which contains no harmful chemicals or toxins so they are BPA free, non toxic and therefore a healthy water bottle. Food grade stainless steel is the best material for water bottles because there is no leaching of tastes or smells into the pure liquid inside. The water tastes as pure and fresh when you drink it, as it did when you put the liquid into the bottle. There is a growing awareness of the toxicity of plastics which makes using a PUNC bottle for water, a very healthy alternative to using a plastic bottle.
