One package of 4 x 5 inch Iron Man 3 Invitations and Thank Notes with envelopes. Let your guests know that it is time for a super get-together with these post card-style Iron Man 3 Invitations. Simply write your party information on the inside and mail them in the envelopes provided. Your guests can then tear off the 2 x 4 inch Stark Industries R&D Department Guest Pass and use it to gain entrance to your lab. (Don't worry. They are perforated.) After the party, send a hearty thank you to your guests with the Iron Man 3 Thank You Postcards that are included in this package.
