I’ve seen these water bottles everywhere.

I’m not 100% sure whether Eco Canteen invented and/or patented the idea, but they certainly trademarked the name, Eco Canteen™.  The point being, these fashionable water bottles are everywhere.  They are trendy & environmentally friendly - in that they are reusable.  In addition, they do not deliver plastic toxins to the body, which happens when a person reuses the same plastic bottle over and over.  Check it out.
