1 star review by user "Tall Guys Wife" on Amazon of a rubber banana that has the words [for scale] on it.
Picture attached shows rubber banana is smaller than real banana.
Review text reads: "purchased this 'banana for scale, but it's way smaller than an average banana. People on social media demand if you're showing something that you use an average banana for scale. I would never deceive anyone with this ridiculous substitute for an accurate measuring tool."
Maybe it is a regional thing? I'm from the US and that is pretty much the size of every banana at my grocery store.
To clarify, by regional I mean that the US disproportionately buys / sells a variety of bananas that is just bigger. Though I'll admit I have not taken the time to google this so 🤷
