Nábrók are a pair of pants made from the skin of a dead man, which are believed in Icelandic witchcraft to be capable of producing an endless supply of money.
In order to make the necropants (called nábrók in the naive tongue) an individual had to get permission from a living man to use his skin after his death. The surviving member of the pact has to dig up his dead friend’s body and peel off the skin of the corpse from the waist down in one piece without any holes or scratches, to make the magical trousers.
The wearer of the pants has to steal a coin from a widow and place it in the scrotum of the trousers, along with the magical sign called nábrókarstafur, drawn on a piece of paper. The coin will draw money into the scrotum so that it will never be empty, as long as the original coin is not removed. As soon as they stepped into the pants, the skin of the corpse becomes stuck to their own. To ensure salvation, the owner has to convince someone else to take ownership of the pants and step into each leg as soon as he gets out of it. The necropants will keep the money-gathering nature for generations. (Source)
