50% Off! Our 5" x 7" Verical Flat (Koala) Pouch gives the look of a flat card but retains a place to contain all your inserts! Place the invite on the front and your rsvp, rsvp envelope and anything else you might like to include in the pocket on the back. This pouch fits into a 7-1/4" x 5-1/4" A7 Envelope. Our A7 Side Flap or A7 Top Flap Envelope would do the job perfectly.
