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 #9 single window 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 fall out and become exposed; so much for a security envelope. Our strong seal will guarantee the safety of your contents.

It can be frustrating to purchase envelopes only to find them flimsy enough to have you worried about their durability during transit. Our envelopes are made of 24 LB White wove paper that will provide a professional look from the box all the way to your destination.
