It can be so difficult to find envelopes that create a strong lasting seal thus forcing you to waste time using glue sticks or tape to close the envelopes. Our invoice envelopes with strong adhesives are designed to immediately create a strong seal so you do not have to worry about your contents being exposed to others.

Unlike weak sealing envelopes that allow your contents to fail out and become exposed, So much for a security envelope, our strong seal will guarantee the safety of your contents.

24 LB white wove paper creates a professional look and feel from out of the box all the way to your destination
