Oh for cripes sake....
With the toys we had, we should have been dead in minutes.
Yes, I survived my wood-burning set and my chemistry set just fine. I don’t even remember any warning labels on them.
The evidence is thin but the reason we see these toys is because they were concocted to replace latex (rubber) toys because of the rather recent determination that some people are allergic to latex.
The rules demand that toys cause no harm yet there is no practical way to define harm.
