Stop collecting comic books and start collecting stickers! Each package of Superhero Party 3-D stickers includes 4 sheets of comic book action words such as kapow, splat, krunch and bam! Our superhero stickers are a part of an amazing 3-D experience you can create when paired with 3-D glasses (sold separately). Pass them out as party favors or award them to the person who does the most heroic deed!
