What is the difference between a #9 Regular envelope and a #9 Remittance envelope?
Both of these envelopes have the same final size of 3 7/8" x 8 7/8", or 3.875" x 8.875".
The difference is the size of their flaps and their utility
These are the perfect size for a return envelope that fit nicely inside of a #10 envelope. They are available with or without a window.
