The world's smallest Christmas card has been created by British scientists - 200 million times smaller than a stamp.
The tiny card, which is 15 microns by 20 microns, even includes an intricate inscription of a snowman and seasonal messages - despite being too small to see with the naked eye.
It was created by scientists at the National Physical Laboratory in Teddington, south west London, who say it is ten times smaller than the previous record holder. A micron is the equivalent to one millionth of a metre.
The card, made on a silicon nitride membrane has a coating of super-expensive platinum, which is worth 0.000002p.
The card is so tiny, about seven quadrillion of them could fit into an average post box - which is 900,000 cards for every person on earth.
