Our 6" Square Pouch is the standard in pouches. Place a decorative seal or wrap on the outside and put your invite on the inside panel. It's a presentation your guests won't soon forget! The Square 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 6.25" Square Envelope. Our Square Envelopes would do the job perfectly.
