How do you get people to come to your Sonic party? Why, just send out Sonic themed Party Invitations! These great little invites come in a pack of 10, with envelopes. They have a nice big Sonic art on the front and it says "You're invited" inside, the guest will see the winged "S" symbol in blue-scale, as well as the details. (Time, day, RSVP, etc) the top of the interior says "It's a Sonic the Hedgehog Party!"
