Each paint we choose to finish our bottles with is made with a durable acrylic resin-based paint, free of lead and other toxic chemicals approved for food use. Because safety comes first.
It also means that the paint can be scratched off if you drop it or scrape it against another object. Careful use of the bottle will prevent this. If it is dropped, the bottle might also get small dents, but there is nothing to worry about in terms of its safety: even if your drinking bottle has dents or scratches, it will continue to serve you well without you having to be nervous for whether any chemicals or toxins can migrate into your food or drink.
