What is the difference between a #9 Regular envelope and a #9 Remittance envelope?

Both the #9 regular and the #9 remittance finish at the same size, 3 7/8 x 8 7/8 inches. What changes is the flap.

• The regular #9 is a standard reply envelope that fits inside a #10.
• The remittance #9 adds an oversized flap for collecting written information.
• Pick remittance for donations and billing replies, regular for plain reply mail.
