The BLACK CUBE is part box, part money. Put simply, it is a box holding money.
You can have your own BLACK CUBE, filled with your desired amount of money. The greater the amount of money inside the BLACK CUBE, the greater the real value outside. You determine the value of your BLACK CUBE.
Everything comes at a price, so does the BLACK CUBE. The price of each BLACK CUBE is calculated as follows:
(production cost of the box) × 12 + (the desired amount of money inside the box)
Why times twelve? Because the BLACK CUBE has twelve edges.
Note that the price is excluding shipping cost. The buyer is responsible for shipping and is to cover all costs.
You get your BLACK CUBE, filled with your desired amount of money. You also get an official certificate that proves that the BLACK CUBE is authentic. Without this certificate the BLACK CUBE is not authentic. The formal aspects of the BLACK CUBE are based on the the amount of money inside the BLACK CUBE. The BLACK CUBE cannot be opened without destroying the BLACK CUBE.
To ask for an invoice, send an email specifying your desired amount of money inside your BLACK CUBE to firstname.lastname@example.org. It is possible to order more than one BLACK CUBE at once.
