Drop Box

The drop box is a device mountable on any wall so long as there is nothing else on that wall such as lamps or another drop box. The front of the drop box is typically placed on the exterior of a building, so that items may be deposited safely to anyone on the other side. The drop box does not require the operation of more than one person, but it will fill up if someone on the rear end does not empty it from time to time, which will disallow you from depositing more items. Be careful to make sure the correct side is facing you when you deploy it, as it may be annoying to remove and place again if you make a mistake.
