Does the humidor have to have an airtight seal?

Cigar tobacco "breathes". Cigars consume oxygen and emit gases into the surrounding air. For this reason, it is important that humidors are regularly aerated in order to provide the cigars with fresh oxygen. Humidors should close so well that a constant level of internal humidity can be maintained. However, a hermetic seal is neither necessary nor desirable.

If the humidor is not opened for longer periods the necessary oxygen level can be maintained by placing a match under the lid of the humidor. Afterwards one should verify that the humidor is able to maintain a constant level of humidity.
