Just saturate your 4 oz. HUMI-CARE jar with a small amount of distilled water and the beads absorb and expand. These specially-formulated beads contain a solution of propylene glycol, so you’re assured of a slow, steady release of moisture and constant humidity of 65-70%. Each refill with water typically lasts 1 to 2 months, and each jar can be refilled for up to a year before replacing. Ideal for 25-150 capacity humidors - grab a couple of jars if you have bigger humidor or multiple shelves.
