Thats crazy.... Ive been shipped 0G plugs before though mailing envelope and have never had a problem.... Ive actually been mailed multiple items like that.
Shadow i know happened and have proof and it has happened to others and i looked on your side and did not see were u shipped any 0g out but there is always some one that knows everything. .most of the time if it's not flat it will rip it right out of the paper. .
And shadow must of your earrings look like they r flat and not round i am just trying to help and make sure on safe shipping so there wount be a problem. .
