HOW BOVEDA WORKS: Boveda 69% RH keeps items fresh by stabilizing the humidity inside a humidifier box. If the air inside your container is too moist, Boveda absorbs that moisture. If it's too dry, Boveda releases moisture into your container to bring what's inside back to life. ADD A BOVEDA PACK RIGHT AWAY TO A HUMIDIFIER BOX WITH NEW PREMIUMS. You can also use Boveda 69 to restore overly dry items to their original flavorful, aromatic state—the way the master blenders intended.
