For those new to this website:
Tamara Rubin is a Federal-award-winning independent advocate for consumer goods safety and a documentary filmmaker. She is also a mother of Lead-poisoned children. Tamara’s sons were acutely Lead-poisoned in August of 2005. She began testing consumer goods for toxicants in 2009 and was the parent-advocate responsible for finding Lead in the popular fidget spinner toys in 2017. Tamara uses XRF testing (a scientific method used by the U.S. Consumer Product Safety Commission) to test consumer goods for toxicants (specifically heavy metals), including Lead, Cadmium, Mercury, Antimony and Arsenic. All test results reported on this website are science-based, accurate and replicable. Items are tested multiple times to confirm the test results for each component tested.

So scary. I wonder if it would turn one of the 3M tests red? Thank you for your work, Tamara!!!
