What a fantastic idea: The World’s Smallest Post Office
Who wouldn’t love a teeny tiny letter? So small you have to have a magnifying glass to read it.
It goes into a tiny envelope which gets addressed, stamped, and sealed with a miniscule wax seal with your initial on it. The letter then goes into a see-through folded coin case and is packaged up with a magnifying glass in a larger glassine envelope, finished off with a large “World’s Smallest Letter” wax seal.
The Postmistress has a traveling setup, with a miniature rolltop desk, but also will take orders online for those non-San Franciso livin folks.
