Envelopes for Every Situation
Before envelopes were invented, letter writers had to rely on sealing wax rather than using extra sheets of paper. This is because historically, individual sheets of paper were quite expensive. As the USA postal system was reformed in the 1840s, rates were lowered and more individuals and businesses alike were able to send letters. Because rates were now determined based on weight and distance rather than the number of sheets of paper, it started to make sense to use a wrapper like an envelope.
