Review on Boveda 72% RH 2-Way Humidity Control - Size 60: Restores and Maintains Humidity Effectively for Cigar Humidors - Convenient All-In-One Solution: Patented Technology for Versatile Humidification - 1 Count Resealable Bag by Leroy Jacobs

I have never been able to keep my humidor at a reasonable humidity level during dry winters after the first year of operation. Fill the built-in humidifier with solution, add a humidifier stick, or a glass: none of these helped my cigars go too dry without constant vigilance. But this little bag worked like magic. My normal desktop humidor lasts about half a year. If you hesitate to buy this or refillable gel, take this one.
