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.
do you need to cut them open? tbf they look prettier this way, but i just keep them in their own paper bag, in a sealed plastic bag
No need to cut them open, but I wanted to make custom-sized packs. You can always nuke the little packs for little needs. But, ya know, I’m a man with man-sized needs.
If you’re gonna nuke 'em immediately before use anyway, do you even need to store them in a sealed bag?
I currently have mine in an uncapped mason jar on my desk, for convenience as I clean house and collect the ones I have lying around in random disorganized places.
