#9 Double Window Security Envelopes

#9 double window security envelopes are specially designed to provide a snug fit for your checks and forms. These aren't the generic loose-fitting envelopes found at big box office retailers. Our envelopes are made from 28 lb. paper stock and feature a window security tint and more space between windows to keep your check amounts private.
