The Humidor Bag is the most functional humidor for the money. They are also very handy to have around because they are extremely compact, and you just throw them away when they are used up. The Humidor Bag will last you an average of 90 days and is guaranteed to maintain a constant 70% relative humidity. Simply re-seal the pouch each time you use it to ensure your cigars remain in 'humidor fresh' condition.
