Hi Tamara, Can a PLAIN glass mug with no writing or image of any sort contain lead or other unsafe metals? Can a stainless steel with no writing or image of any sort contain lead or other unsafe metals? I would be so very grateful if you could send me a response to my email. Thank you very much for your time and the work that you do.
