Handle with care
You would not be happy if you received your parcel and it looked like this. The bright stickers should have been enough of a hint to the delivery person that they needed to handle them with care because the contents were fragile and corrosive.
Not only should the recipient receive their goods in top condition, but also everyone along the way should be safe. By the looks of the burnt edges and holes in the box, it is clear that this was not handled safely at all.
