Humidor

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; the Colorado Rockies Major League Baseball team stores game balls in a large humidor at their home stadium, Coors Field, to counteract the effects of Denver's high altitude and generally low humidity. Humidors of all sizes use hygrometers to keep track of the humidity levels.
