In France, children celebrate the first day of April by pining paper fish to people's back, hoping they won't notice. I never grew out of it.
These fishes were designed to complement any urban outfit. Cuz, you know, it's a French prank, it has to be stylish, too. :P
Cut out, add a string and a bit of tape, or just tape, and tape it on your friends back when hugging them. Enjoy!
