Review on Amazon: A banana for scale should be to scale https://a.co/d/aAZPaX4

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."
But there's a flaw. You've already lost it.
Maybe a different fairly popular but far less likely to be lost pen. How about Lamy Safari (Vista and Al-Star can be used too - same dimensions).
