The Boveda Humidification System for 75% Cellars is effective in preserving the aromas of cigars. In addition, it makes life easier for tobacco lovers. Indeed, to use this accessory for smokers especially for small cigar humidors, just put the humidifier bag in the cellar. It works, in fact, without water and without adjustment. Once installed in the mini cigar cabinet, the life of the pouch 6.5 cm long by 5.8 cm wide is one year. Another advantage of this product for humidification: it becomes rigid when it is necessary to change it.
