There once was a man named Drew,
Who bought a toothbroush he knew he could chew.
If the directions he'd followed,
He wouldn't have swallowed.
So back up, the toothbrush, he threw.

Heathrow, Reading station as well, though they are one-piece and not two like the patent above. It does seem to be the same as the actual patent though

It's a real good idea actually. I used it once at the airport when you need to brush your teeth while you don't have a toothbrush with you. It wasn't as good as a real toothbrush, but it did made my teeth feel a bit clean and fresh.

Not for children, elderly people, or anybody else at risk of choking.

It's a real patent in the Us. I think you are supposed to clean your teeth by chewing on the end.

Is the patent a real patent? With the US or the world? I don't understand from the picture how it is supposed to work.
