"Perfect for birthdays, and inspired by the fun and dynamism of comics, the card is embedded with a cracker snap, and goes 'bang' when pulled open! Each card comes with a joke, a paper superhero mask, and has slots to hold a gift voucher if desired; providing an innovative gift experience not provided with conventional greetings cards. Also provided in the pack is a bright yellow envelope, an instruction guide and an envelope sticker saying 'pull me!'

Available in a range of different designs inspired by comics and social media, see other product listings for additional cards. Message inside reads: 'celebrate with a bang!' The card is printed on an uncoated board to recreate the texture of comic books, with gloss varnish details."
