Certain types of plastics, I think? That do that kind of shrinking act as a result of coming into contact with the heat and/or moisture and/or oils on your hand.
I’ve had the same thought: it shrinked because of the heat or moisture of my hand, but I didn’t know there was a plastic that does that. It’s interesting though, I’ll try to uncover some info.
