I too have a concern about product materials but, mine stems from the material guide section. For example, when you click on "crystalessence" in the description of an item, you are taken to the material guide section that does in fact tell you all about the crystalessence material but, it does not say whether or not it contains pthalates. I really would like to know in the material guides which materials contain pthalates and which do not. I do understand that most materials that are pthalate free will say so under the properties tab when viewing the item itself but, it's just kind of confusing when the description doesn't say whether it's pthalate free or not and the material guide doesn't either so, it leads me to beleive it does in fact contain pthalates. I actually did a google on crystalessence to see if I could find any info on whther it contained pthalates but, couldn't come up with a yes or a no there either. Just a suggestion to try and help clear things up.
