Buy Boveda (formerly Humidipak) 49% relative humidity starter kit for guitars for worry-free wooden instrument storage. Improper storage is the greatest constant danger to the condition of a wooden instrument. Until Boveda, humidified storage meant refilling awkward and unreliable sponges, snakes or discs. Those products only work 1-way, they add humidity whether it’s needed or not, while Boveda is the world’s first 2-way humidity control.

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 humidity control provides the cleanest and most purified humidity of all other products available on the market today.
