Despite all that, many Kiwis have spent their life oblivious to one detail on the package. And now a Facebook post - by Christian Hull - has drawn attention to it.
The comedian posted a photo of Arnott's Shapes boxes neatly stacked in the supermarket, with this caption: "The white part of the Shapes box is the actual shape of the biscuit inside".

We can all talk about how obvious it is now but, when the photo was first posted by Hull, the internet immediately went into meltdown.
"YOU CAN NEVER UNSEE THIS", Hull commented on his own post.
The post has been liked more than 16,000 times and received more than 8000 comments.
