This goes in the category of “Things in my home that I never thought to test until now!” This is a lunch box/ food storage container made of stainless steel. My husband pointed out that the little moving parts that make up the top of the clasp system are actually yellow brass. I hadn’t noticed that before. When tested with an XRF that little component came in at 22,500 ppm lead. This is the part you touch with your fingers to pop the lid open before you eat whatever is inside! #Gah!!!
