Miniature love letters penned for Valentine's Day

Who says romantic gestures have to be big for Valentine's Day - the World's Smallest Postal Service has a tiny alternative.

Based in San Francisco, staff will transcribe your words of undying love in tiny letters, onto a sheet of paper no bigger than a stamp or an equally tiny card.

It is then carefully folded and placed into an even smaller envelope and addressed to your loved one with an almost microscopic stamp.

But don't worry about them disappearing in your postman's sack, it's then put in a less Borroweresque package… along with a x10 magnifying glass.
