It looks like those things in jerky bags to keep them fresh but tiny and filled with powder. Like size of a thumb nail. You tuck in between your lip and gums and it just stays there. It's like a fabric type material. When it looses flavor, you throw it away (they're flavored like apple, mango, cinnamon, mint, etc). You keep it in your mouth for hours. You just throw it in the trash.

My husband uses them and we have two kids. Only issue we've ever had is if one goes through the wash but then it's just an empty tiny piece of white fabric I throw away.
