I like to keep fresh breath mints in my car. They come in a box like this:
The problem is they rattle in two ways:
The box is metallic and it rattles against the glove compartment (or other compartment) of the car
Inside the box, the mints start to rattle once the box is less than 1/2 full.
Short of always filling the box and wrapping it in a sock, what are some ways to prevent the rattling?
