Planning a surprise party? These invitations are specially designed to invite friends to the surprise party. Each invitation is designed to look like a paper bag with a black cat that pulls out. The outside says "Shhh! Don't let the cat out of the bag!" The cat is holding a sign that says "it's a surprise party!" with spaces to write who the party is for, date, time, place, and the RSVP number. Includes envelopes for mailing.
