I bought these for my toddler because the description says "polypropylene," which is one of the less bad plastics. The forks are useless but the spoons are the perfect shape, size, and depth, so I came back to order more, and saw the Prop 65 warning. I've researched that warning since my sister lived in CA, and I know that it's not a perfect system, but it also provides important consumer information. And guess what? None of our other baby products have a Prop 65 warning, so the manufacturer's response is just irresponsible. I sent them all back. Why would I buy baby products with a Prop 65 warning when there are plenty of baby products to choose from without a Prop 65 warning? The manufacturer needs to get it together.
