Kosteudensäätäjä Boveda 320g

Boveda' is a 2-way humidity control which on the one hand removes too much moisture, but on the other hand also gives off moisture when needed. This works by the natural principle of osmosis:
Each 'Boveda' pack contains a bag of natural salts and a bag of pure water. Both bags are connected with a permeable membrane. Thus, the salts and water can travel through the membrane, absorbing moisture as needed, or releasing the required amount of moisture. This regulation keeps the relative humidity in the storage box constant, either at 58%, or at 62% 

And the application of the moisture regulator is more than easy: just put the 'Boveda' pack in the storage tin! When the pack gets hard, it's time to replace it. The more packs are used in a storage box, the longer they last. But do not worry, the 'Boveda' packs never release too much moisture!
