Window Envelopes

People receive bills in window envelopes; promotional materials may also come in a window envelope. These types of envelopes are not as secure as commercial envelopes, since the clear flimsy plastic covers the window. Additionally, there is no need to address the envelope because the name and address appears through the window. Some envelopes even have two windows allotting space to display the sender’s address.
