BROWN BAG Kraft A1 (4 bar) Envelopes

Brown Bag Kraft RSVP Envelopes Brown Bag Kraft Response card envelopes or note card envelopes are designed to fit A1 or 4 bar RSVP cards that measure 3 1/2 x 4 7/8 inches.  Measuring  3.625”x5.125”, this type of envelope is also known as a 4 bar envelope or an announcement, wallet, or response envelope.  This is the smallest type of envelope that the U.S. Postal Service will deliver with standard postage.  PLEASE NOTE: Due to the rough texture of the Brown Bag Envelopes, some customers have had some difficulty sealing the envelopes with the moisten and seal flaps. We recommend using a tape runner adhesive to help with the sealing.
