It's styled like a miniature gear lever with the 6-speed pattern on top, which is instantly recognisable to anyone who drives a manual and completely baffling to anyone who doesn't.
That's rather the point. It's a small signal to other people who care, and the people who care will spot it on a keyring from across a car park.
It's light enough to live on keys without adding noticeable weight, which is the usual reason novelty keyrings get quietly removed after a few weeks.
It works equally well on a backpack zip or hanging from a rear view mirror, so it fits whatever the recipient actually wants to do with it.
At this price it's an easy stocking filler or Kris Kringle, and it's one of the few car-themed gifts that isn't another air freshener or a novelty mug.
If you're buying for a teenager who's just gone for their licence in a manual, this lands particularly well. You're acknowledging something they're genuinely proud of, and at this price you can add it to whatever else you had planned.
It suits car enthusiasts of every age — the P-plater who just learned to drive a manual and the dad who's been driving them since before anyone asked his opinion.
You're giving something cheap that gets a genuine grin, which is a better outcome than a lot of more expensive gifts manage.
It's worth checking they actually drive a manual before you buy. The joke is specifically about that, and handing it to someone who's driven an automatic for twenty years is a small but noticeable miss.
