Each bulk case contains 100 large Boveda, each of which are overwrapped in high-barrier plastic to ensure maximum shelf-life. These are the same Boveda packs you'll find in our retail cubes, without the carton. This frees you up to be able to buy Boveda in bulk quantities without paying for retail packaging.
When do you use a 60 gram Boveda? Whenever it fits in your storage container. Boveda will never humidify beyond the RH on the pack, so there's no such thing as "too much". You want to think in terms of using at least the minimum because the more you use, the more efficient Boveda works and the longer they last. 60 gram Boveda are commonly used in mason jars and large bags. They can last 6+ months depending on how often the container is opened, you'll know it's time to replace when the entire Boveda begins turning hard.
Each Boveda consists of a specially prepared saturated solution of pure water and natural salt. This saturated solution is contained within a water-vapor permeable "reverse osmosis" membrane. Within a closed desktop humidor Boveda maintains a predetermined level of (RH) by releasing or absorbing purified water-vapor, as needed, through the membrane.
Boveda provides the cleanest and most purified humidity of all other products available on the market today.
Note: Do not mix Boveda RH levels within the same humidor, and do not use Boveda in the same humidor with other humidification products. They will fight against each other and reduce the efficiency of the Boveda.
