• WHY THIS BOVEDA: Manages humidity in an instrument display case or utility case. Works automatically. No day-to-day care! No rewetting! Protects fretted, bowed & woodwind instruments from humidity fluctuations. A Size 320 maintains the ideal humidity level for an instrument for months. NATURAL INGREDIENTS. Trusted by over 3 million people to protect & maintain items at the perfect humidity level. WE GUARANTEE QUALITY! If you’re not 100% satisfied, reach out for a full refund for up to 1 year.
• 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 display or utility 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 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: Use 1 Size 320 PER INSTRUMENT in a display case for up to 6 instruments. Remove the clear plastic overwrap before using. Do NOT open the brown humidity packet inside. Do NOT remove the Boveda pack from its brown cardboard box for use with instruments. Simply place the Boveda in your instrument display case and close the door. Or affix the pack to your case using a Boveda Mounting Plate (available separately). Replace this pack every 3 months. NEVER MIX the 49% with any other %RH.
• WHO IS BOVEDA FOR: Boveda 49% RH is for acoustic & electric GUITAR players & musicians who play WOODWINDS & BOWED INSTRUMENTS. Professional musicians, band & orchestra leaders, instrument techs, music teachers, hobbyists & student musicians use Boveda packs for easy & precise humidity management in instrument display cases. NO DAILY MAINTENANCE! Don’t risk damaging an instrument by adding water to sponges and snakes & forgetting to refill them. WHY RISK A WARPED OR CRACKED INSTRUMENT?

Product description Love Your Instrument—for effortless humidity protection, use Boveda. Having been in the industry for 25 years, Boveda is a trusted and experienced brand in relative humidity control. But what does that even mean? Relative humidity (RH) refers to the percentage of humidity within an environment. In other words, it answers the question, 'how moist or dry is the air in my instrument's display case or utility case?' Boveda's founders & scientists discovered that the right RH has a huge impact on a wood instrument's performance & sound & safeguarding its construction. Using Boveda, you'll maintain a precise moisture level between 45 and 55% RH. Use 1 Size 320 per instrument in a display case, up to 6 instruments. (For a musical instrument display case holding more than 6 instruments, we recommend using a dedicated humidity management system.) Now forget about the pack until it starts to get hard. Once it does, just switch it out with a replacement pack. Each Boveda 49 RH pack can last you up to 6 months. Its lifespan depends on how often you open your case, how airtight your case is, & how dry or humid the climate you live in is. USE BOVEDA 49% RH HUMIDIFIER/DEHUMIDIFIER PACKS in an instrument display case or utility case to maintain the right humidity for: GUITARS, including acoustic, electric, electric bass, guitarrón, hollow-body, nylon string & semi-hollow body; FRETTED INSTRUMENTS, including banjo, mandolin & ukulele; STRINGS, including cello/violoncello, double bass/upright bass, hollow-body bass, viola & violin; & WOODWINDS, including bass clarinet, bassoon, clarinet & oboe.
