 * First cut out the keys and ring in one piece, as here shown.
 * Now cut only half through the cardboard along the eight little dark lines,
 * and similarly cut half through on the eight little dotted lines on the other side of the cardboard.
 * Then insert a penknife and split the card below the four little squares formed by these lines,
 * and the keys will come apart with the keys loose on the ring and no join.
