Cheap things from China often have recycled or re-purposed parts. I had an antenna that came apart and is actually a tape measure with some rubber over it just soldered right to a threaded connector.
The aim with simple antennas is to get their length right to match the radio waves. Often at 1/4 of the wavelength.
The type of metal an antenna is made of matters, as the speed of light is different in different materials.
I suspect if it doesn’t work well it’s because the manufacturer either made it the wrong length or used a fibreglass tape measure rather than a steel one
It “works” but isnt perfect. The length matters, but it does work and is the right(ish) length. I don’t have the instruments to test it properly.
More, it just isnt very practical because it doesnt work much better than a small whip antenna. I do have a more powerful radio I need to test it on eventually, but it uses the wrong connector for that and I have to buy an adapter
I would say it most likely came from a Chinese toy factory. They really have a creative way to use recycled/unused/broken parts. Sometimes it can get worse though.
I desperately want to know if this is:

I think that must be fairly common as I remember a video talking about using a tape measure being used on a satellite.
I’ve found it! I thought it would have been Scott Manly, but it was a question in Tom Scott’s Lateral quiz: https://www.youtube.com/watch?v=RrsBn1pzQFE
Uh, did the antenna work? Not a RF guy but as far as i know, the dimensions of the “wire” matter.
And btw, cheap chinese plastic things are likely to leak some hazardous chemicals.

Right but what about this case specifically

don’t dismiss creative toddler
