Our 5" x 7" A7 Booklet Pouch is a folded card but with a pocket! Place the invite on the right side and your rsvp, rsvp envelope and anything else you might like to include in the pocket on the left side. Top it off with a decorative seal or wrap on the outside. This pouch fits into a standard size A7 Envelope. Either our A7 Top Flap Envelope or A7 Side Flap Envelope would do the job perfectly.
