The Humidification System for Cellar 320g 84% is a humidifying bag offering a great autonomy. This bag ensures the maintenance of 84% of the cigar cellar in which it is placed, with the accuracy of 1%. The design of the system is such that only water vapor is released. Your cigars are thus preserved in optimal conditions, without risk of parasitic perfume. The large size of this bag ensures a very long autonomy, up to six times that of a conventional bag. This system can also be used to ensure the preservation of a musical instrument.
