Humidor
A humidor is any kind of box or room with constant humidity that is used to store cigars, cigarettes, or pipe tobacco. For private use, small wooden boxes holding a few dozen cigars are common, while cigar shops may have walk-in humidors. Humidors can be used to maintain consistent humidity level for other goods; 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 low humidity. Many humidors use hygrometers to monitor their humidity levels.
