A humidor is a specially designed container used to store cigars and maintain their ideal moisture levels. It typically features a sealed environment that helps regulate humidity, which is crucial for preserving the flavor and quality of the cigars. Most humidors are lined with materials that help retain moisture, and they often come with a hygrometer to measure humidity levels. Humidors can vary in size, from small portable boxes to large cabinets, catering to different storage needs. They are commonly made from wood, glass, or a combination of materials, and some even include built-in humidification systems to ensure consistent moisture control.
