World's Smallest Postal Service

While surfing online I found this cutest thing on web. Ever wondered on sending the smallest and tiniest letter or greeting card across? Here is someone who can do this for you - World's Smallest Postal Service .

And this is how it works:

 "You write a letter and it is transferred onto a tiny 1 inch paper. It is placed in a tiny envelope with address, stamped and wax sealed. The letter is then securely put into a see-through folded coin case and is packed with a magnifying glass."

And it's not just letters you can send but invitations, custom cards and even packages. And here's the coolest video of the coolest mailing kit.
