Humidifier - Travel Humidor 4-pack: Humidipak 62% - By Boveda

The same sophisticated tests that indicate the ideal water content of a given item has been done on various herbal strains and it's been determined from a scientific standpoint that 62% is the ideal storage humidity for herbal medicine. This is reinforced by the fact that herbal storage at 62% maximizes smell, taste, color, texture and burn rate. And once you've cured medicine at 62%, you'll find you've stepped into a new reality. You can now successfully store medicine indefinitely within the precise freshness window as long as you have an air tight container and a 62% Humidipak. And since each Humidipak is completely maintenance free and lasts for months, we've finally found the holy grail. That's not an overstatement.
