A humidor is any kind of box or room with constant humidity, used to store cigars, cigarettes, or pipe tobacco. For private use, small wooden or acrylic glass humidor boxes for a few dozen cigars are used, while cigar shops may have walk-in humidors, sometimes consisting of a whole floor. Humidors can be used to store other goods for which a certain level of humidity is desirable. Humidors of all sizes use hygrometers to keep track of the humidity levels.
