You need a good macro lens to get a photo of the "micro SD" card that came with my new phone: it stores 1 gigabyte* of stuff and is approximately the size of a baby's eyelash.
Here the card is modelled by a Lego fireman in a brazen bid for more comments/faves, since everyone knows all the girls love a fireman.
* (In leading-edge technical circles, a gigabyte is referred to as "a giggle".)
