Oxygen Absorbers, 50cc, Pack of 200
Designated by the amount of oxygen (in cubic centimeters) they will absorb, a “50cc” oxygen absorber is the perfect size for something a quart size or smaller. Use more than one for slightly larger containers. 200 come in a vacuum-sealed package.
When you open the pack, have the jars or items ready and only use what you need. Then use your vacuum sealer to protect the rest. You could also place the rest in an airtight jar or container until ready for future use.
