Indications

2-way humidity control for instruments and instrument cases

Directions

If you're starting with a very dry case, you can expect that the first set of packs won't last as long as subsequent packs, as most guitar cases have twice as much wood as the guitar. Season your guitar case first for best results. Large kit includes four (4) Size 70 Boveda and two (2) leak-resistant fabric holders. Lasts between 2-5 months in a seasoned case. Longevity depends on time of year, case quality and ambient RH levels.

• HOW BOVEDA WORKS FOR MUSICAL INSTRUMENTS: Boveda 49% RH protects wood instruments & their accessories by stabilizing the humidity within the ideal range—45–55% RH. If the air inside a case is too moist, Boveda absorbs that moisture. If it's too dry, Boveda releases small amounts of water vapor into the case. Wide humidity fluctuations will cause the wood to expand or shrink, which puts stress on the instrument & degrades its performance abilities.
• CHOOSE BOVEDA: Boveda's the only patented 2-way humidity control solution with more than 25 years of experience. Using saltwater in our humidity packs, we provide the fastest, most precise humidity control in the market for wood instruments. When you invest in an instrument, you want to ensure you take care of it to produce optimal sound. Boveda is the only humidity solution that can do so within 24-48 hours.
• HOW TO USE: Always insert Boveda packs into the included protective Boveda Fabric Holders before using in an instrument case. Remove the clear plastic overwrap from the packs before using. DO NOT cut or open the brown humidity packet. Slip the packet(s) into the holder(s). Place in case and close the lid. BOVEDA DOES THE REST. Replace every 3 months. NEVER MIX the 49% with any other %RH.
• WHO IS THIS LARGE BOVEDA KIT FOR: Players of acoustic guitar; hollow-body guitar; nylon string guitar; semi-hollow body guitar; guitarrón hollow-body bass; cello/violoncello; double bass/upright bass; bass clarinet; or bassoon.
