Window Envelopes

Window envelopes have a hole cut in the front side that allows the paper within to be seen. This allows the address to show through so the envelope itself does not need to have an address applied. Find the lowest prices and free shipping for printed business envelopes, size 10 envelopes, window envelopes, commercial envelopes, business reply envelopes, and more. Transparent address panels of window envelopes must be completely crease free and the contents must not be able to shift, thereby obscuring the address. There exists no international standard yet for window envelopes and matching letter head layouts.
