Miniature Postal Service

In San Francisco you can find the World’s Smallest Postal Service which actually is up and going. What they basically do is to receive normal letters from people and write them in a smaller version before they wrap it and put it in a sealed envelope, and send it in ordinary mail.
It only cost $8 dollars to use their service, and it’s worth it, because why not receive a tiny tiny letter in the mail than the ordinary boring ones. You can use it as a joke or a prank to a friend, or maybe only use it as a surprise to someone. You maybe wonder how the mail man understands the small writing, but don’t worry, every small letter has a magnifying glass on it, so it can enlarge the letters easily.
