Cut 'em open and pour them in a jar with a tight seal. When you need a pack, microwave hell out of some and rubber band them into a piece of coffee filter.

The colored beads indicate how water saturated they are. When they're nuked and dried out, they change color. YMMV as some manufacturers use different colors or none at all. Whatever. Nuke 'em and reuse.

It's an exciting hobby.

Just an FYI if you encounter any with the blue/pink moisture indicator beads rather than this orange/green kind, I wouldn't put those near anything you intend to eat out of.

The cobalt chloride indicator is somewhat poisonous.
