This gift box looks like it's impossible to open it. But you can, if you know the trick. It has an inside space of 70x70x15 mm to hold banknotes, concert tickets, vouchers, jewellery or a wedding ring. A hidden magnet and a steel ball lock the box. If you hit the box with the printed question mark facing down hard on a table, the ball will detach from the magnet, falls into the hole and you can slide the upper part of the box diagonally to open it.
