Pet, smoke, sun, dust free. Only used for one season and then stored away. I'm sorry, I don't have the coa .It got lost in the shuffle but there are no chips on the animals or logs that I can see and I have the original box.  Limited edition of only 1500 pieces. 2003.  Maybe someone would like to add these to their nativity. I'm not sure what they are made out of possibly wood ???
