A humidor is a humidity-controlled box with components that create an ideal environment for your cigars to be stored in. But without humidifiers, cigar humidors are just boxes. It does control the moisture inside but it’s the humidifier that creates the condition that helps your cigars age properly without drying out.
Humidors come in different shapes and sizes. It can be a big humidor box almost like a walk-in room or it can be a small travel-size case. It depends on your need which one you prefer. But it should have a good seal to maintain the temperature and keep your cigars moist always.
