The security seals secure and protect the package of the sender at the same time secure the feeling of the sender before, during and after the shipping process of the package. If people never had the initiative to create security seals then everyone will still be carrying important documents by themselves just to send or give the document to the receiver even if it will cost them a large amount of money or even if it will cost them to travel half across the globe to hand it over. Since the package is really important they don’t have much of a choice back then. But now people had the initiative to create a device that enables the receiver to identify if the senders package has been contaminated or has been touched or seen by other people. How awesome is that? So if I were you, I’d start using one now.
