Klean Kanteen: the Original Stainless Steel Bottle In 2004 Klean Kanteen® introduced the first personal hydration bottle made from stainless steel to give health and environmentally conscious people an alternative to plastic. We have yet to see another bottle company, stainless or otherwise, that makes a product comparable to our high quality, handcrafted bottles or that commits to strong environmental and labor standards. When you buy a Klean Kanteen® you're getting a handcrafted bottle designed to last a lifetime. We use an extremely high quality metal that will remain stain and rust resistant for decades. http://www.environmentservices.co.nz/
