These are made with acid-free archive
grade 12mil PET plastic. 100% safe for your collection. These will
protect what affects the value the most, the box!
There is another source for this type
of protector that advertises that theirs are made with PVC plastic.
PVC plastic has acid in it and is not supposed to be used for items like
this. Don't just take our word for it. Google it and do your own
research. If you have purchased those in the past we would encourage
you to not leave your Pops in those even if you don't buy these.
