When we think of sending out event invitations, we think envelopes. The first known envelope dates back to around 3200 BC in the ancient Middle East. This envelope used hollow clay spheres and were molded around financial tokens used for private transactions. Paper envelopes though were first made in China where paper was invented by the 2nd century BC and were subsequently used to store gifts of money.
