These are your traditional RSVP card sets, including the card itself and an envelope printed with your address as the designated recipient of that returned card. These do not include stamps. If you are taking a more modern approach and having your guests respond with their attendance online, I would suggest adding an “additional card” to cover that product, since you will not need the addressed envelope and extra cost that comes with that.

RSVP cards are 3.25 x 4.875 inches.
