One 8 count package of 4 inch x 5.75 inch prismatic Birthday Cake Invitations with white 4.25 inch x 6 inch envelopes. These fun invites open upwards to reveal the party information inside! There are lines for the date of the party, time, location, who it's to, and an RSVP number. The text and cake on the front of the card is underlaid with shiny silver detailing that shimmers when you move it! Seal these envelopes with some fun stickers, and add a little confetti inside for some extra shine!
