Bad sign. In fact, shipped packages that arrive at Customs are not manually opened and then hastily closed back up. Even if inspections are carried out at random, customs are equipped with RADIOGENIC equipment, that is, tools with vacuum tubes installed for the emission of X-rays that determine what kind of object the suspect package may contain. It is necessary not to take into account the slapdash answers, because in distance selling, especially in Eastern countries, everything is often hanging by a thread. But these are things that are now well known.
