humidor is a box, room, or cabinet usually made out of wood that
contain a device that maintains a predetermined humidity. Usually
called a “credo” a humidor often comes with a hygrometer to
measure the humidity in the closed area. Occasionally a humidor will
come with a thermometer to measure the temperature; but is
unnecessary. A humidor is used to maintain the same environment from
where a cigar was born I the warm humid environment of the tropics.
