Way back in 1820 the British paper merchant Brewer was folding a piece of paper, wrapping it around a letter and sealing it
and thus the prototype of an envelope was born. Now we are in the 3rd millennium and that early effort has given birth to
a great many descendants.

Inserting wallet or safety wallet – today's envelopes are only distantly related with the original one. However, we are still talking about ‘envelopes’ even today. The companies of the Mayer-Kuvert-network have decided that the envelope concept is out of date and therefore the Europe-wide leading manufacturer has now launched the "MAILmedia" era.
