Well, about two months ago i bought this ---> http://www.mysticunicorn.com/amu_clay.html from a store. As you can see the information given in this page was also written on the packaging. Well, i don't actually believe that it can posses a magical quality but if anyone knows more about this seal (if it symbolises something or if it can actually have a magical power) please tell me. Any extra information you can give me is very well apreciated :)
Sorry for any mistakes on the text.
Blessed be :)
