unactivated or tampered? If the expiration date does not match the packaging it could be tampered with. If just unactivated then that's less of a concern. It might be hard to tell they are tampered with, the ones I got were VERY good. No extra or different glue, just a few marks on the inside where they had torn out some glue and tried to make it look like that's the way it was supposed to be. Nothing on the outside of the package to indicate it either.
