I don't know. I think it's one of those - buy and use at your own risk. The store knows 'they are covered'.
and I think the proof is derived straight from the coporate headquarters, all these craft stores are franchaises and under the rules, laws and regulations of the corporate offices. 'Their' lawyer knows what is deemed specifically for 12 and under and they are covered.
It may be that in the near future the items will have to be marked.
I was at Joann this weekend and looked at a couple of items that are specifically for this age group. I did not see anything that says CPSIA approved but I don't think,(and i don't know) but i don't think that this whole problem has been specifically outlined and or people and companies told what has to be done to make the the public knows which products are affected by the law. And I think part of that problem is because the law is still going through changes.
