Our 4 gram packs are the appropriate size for smaller enclosed spaces, like small pill jars and baggies. Boveda is scientifically engineered to maintain a precise relative humidity in an enclosed space, and our 4 gram size is available in 62 percent RH.
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 an enclosed container, 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 container, and do not use Boveda in the same container with other humidification products. They will fight against each other and reduce the efficiency of the Boveda.

A must have for any smoker. Works with food as well. I wish they had options to buy more for a better price though .

These little packs are awesome for reviving some older flower. Way better than some of the other kinds I’ve tried. Would love it if they included a pack with every order. (like a couple other places I’ve ordered from) For the cost of them though – I’ll be getting a couple each time I order just to make sure I have fresh ones. As it sits, I have two packs per 1/2 ounce container and that seems to keep them from turning into hay for a couple months.

I just kept it in the silver bag that my weed came in. Worked great.

These are a game changer, Boveda packs are the best thing to happen to cannabis since growers started crossbreeding! These will bring the life back to even the most driest strains, and keep your current smoke fresh; 2 way moisture control.
