Our envelopes are made from 70 lb. paper stock and provide a snug fit for your checks so they don't move about.
We use specially tinted windows for additional document security, providing a blurred image when the check or form is not directly against the window. The inside of the envelope also contains a printed security pattern.
For additional privacy, our double window envelopes include more space between the top and bottom windows to keep your check amounts private. The top window is also wider to display both your logo and address.
