No more hydrating sponges, hoses, discs, soap dishes or whatever else you’ve tried (and dried out) in the past. Boveda eliminates the hassle of these 1-way humidification methods, which spike humidity when you add water then take a nosedive as the water evaporates.
Each Boveda consists of a specially prepared saturated solution of pure water and natural salts. This saturated solution is contained within a water-vapor permeable "reverse osmosis" membrane. Boveda provides the cleanest and most purified humidity of all other products available on the market today.
