Boveda’s 2-way humidity control technology automatically protects your wooden instrument against warping, cracks and other damage caused by lack of humidification or too much humidification. Boveda maintains a constant 40%-50% relative humidity level within your instrument’s (closed) case.

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.

If you’re just getting started using Boveda, you can expect that the first set of packs will not last as long as subsequent packs. The reason is simple, most guitar cases have twice as much wood as your guitar does. All of that wood needs to be humidified!

We recommend seasoning your guitar case first for best results. It’s the same idea and process as seasoning any wooden humidor. Simply place 4 Boveda 72% RH in your case and wait about 2 weeks. The moisture from the Boveda will absorb into the wood of your case and make your regular 49% RH Boveda packs last longer.
