Yeah, it probably depends on the place. I've worked in logistics for a while... since everything is like drop shipped from other countries and manufacterers and all of that jazz there are usually tracking and packinging slips. So if a label on a box gets messed up for some reason or a barcode isnt being read... u open the box get the slip type the shit in and re-print and weigh the package. so it can be opened but like i said, depends who's shipping it.
