Our 5" x 7" A7 Vertical Pouch is the standard in pouches. Place a decorative seal or wrap on the outside and put your invite on the inside panel. The A7 Vertical Pouch opens into a tri-fold with a pocket at the bottom - perfect for an rsvp, rsvp envelope and anything else you might like to include. It folds up to fit into a standard size A7 Envelope. Either our A7 Top Flap Envelope or A7 Side Flap Envelope would do the job perfectly.
