This is really a novelty but I suppose it works. It's a clip-on camera. It folds into a box when not in use. Then you rock open a couple panels and snap it onto a 110 cassette, and you've got a camera. And it has a ring so you can hook it onto your car keys and use it as a big ol' fob.
I've got a couple of these, but never used them so I can't attest to the quality. Considering that it uses 110 film, the bar is set so low to begin with that it probably doesn't matter.
