A very cheeky Calculator Enamel pin. We all used to play this game in school, what rude words can you spell on your calculator in maths class and boobies was always the funniest! 5318008 is a number that will always make us laugh.
Great for maths geeks and fans of childish humour everywhere!
It measures 30mm from top to bottom and is made of a dyed black pin with soft enamel,
