HOW IT WORKS: Our patented two-way humidity controlled Boveda packs compensate the atmosphere inside your humidor. When water vapor is needed, Boveda releases the cleanest and most purified humidity. When there is too much moisture in your humidor, Boveda absorbs the excess. With Boveda, you do not have to adjust any valves or figure out if you put in too much or too little water and you will never have to fill or refill your device with water again - ever. | RESTORE & MAINTAIN: Boveda is the most effective way to properly age and store cigars at home. Simply place the Boveda packet in your travel, desktop, electronic, or wooden humidor right on top of your cigars or use our Boveda Holder. If your Boveda is wrapped in a clear overwrap, remove the overwrap before putting Boveda in your humidor. One of the best benefits of Boveda is that it is maintenance free - all the guesswork has been eliminated. | PRECISE HUMIDITY CONTROL: Automatically restores and maintains humidity in any type of cigar storage-desktop humidors, cabinet humidors, travel humidors, wineadors, coolerdors and tupperdors. You?ll experience a new cigar experience with Boveda-Protected packets. Boveda?s patented formula uses all-natural salt and water to ensure an exact Relative Humidity (RH). Choose from four different RH (65%, 69%, 72% and 75%) and place Boveda in your humidor or container and close the lid-it?s that easy. | 75% RH: Which RH pack do you need? The 75% accommodates a high amount of moisture loss, allowing the humidor to maintain proper RH. Used for humidors at high altitudes and in desert-like conditions. This is the most versatile Boveda ever! Use in any size humidor! In larger humidors, it?s more condensed power. ONE (1) Size 320 = FIVE (5) Size 60. In smaller humidors, it?s long-lasting maintenance-free cigar care. In a 25-count humidor, the Size 320 is good for up to 1 year! | ABOUT US: Boveda devoted the past 23 years to the science of two-way humidity control, we know you will benefit from our commitment to precision. Becoming the global leader in any category does not happen overnight, but Boveda did this and continues to do so since 1997.
