This week, we visited Indigo, a large Canadian bookstore, to look at their Back-to-School items. We picked a wide range of items for parents and tested them for heavy metals.
The results were better than what we used to find in a typical Canadian house!
Follow us for more and book your own home or mail-in testing service.
