Hallo. My parcel has been stopped at the customs office, in order to get it back I need to have a bill or an invoice from you. Are the underwears original, genuine? The customs office will call the manufacturer to learn if there has been an authorization for the production. If the goods appear to be not original, they will be confiscated by the customs office.
