Cigars need precisely controlled temperature and moisture levels in order to keep them fresh for long-term storage, and without a humidor, you won't be able to keep them at the right humidity. Without proper storage, a cigar will lose its quality in less than two weeks.

How long will cigars last without a humidor?

Without a humidor, you just need to smoke your cigar more quickly. A cigar will stay fresh in a ziplock bag for just 2 to 3 days. If you can't get to your cigar within that period of time, add a Boveda to your ziplock bag or other container, like a tupperware dish.

Can you leave cigars in the box?

Cigars that are kept in their factory boxes will stay fresh up to a month on average, even after opening. By placing the entire box in your humidor the cigars will remain fresh indefinitely, just as they would if you removed the cigars, but it depends on how you plan to store the boxes, too.
