Protects fretted, bowed & woodwind instruments from humidity fluctuations to maintain ideal humidity in an instrument case. For use in Boveda Starter Kits or Fabric Holders. NATURAL INGREDIENTS. WE GUARANTEE QUALITY! If you’re not 100% satisfied, reach out for a full refund for up to 1 year. HOW HIGH-ABSORBENCY BOVEDA WORKS FOR MUSICAL INSTRUMENTS: ABSORBS 3X MORE MOISTURE than Boveda 49% RH! Stabilizes the humidity within the ideal range-45-55% RH, even in extreme humidity. 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: Trusted by over 3 million people to protect & maintain items at the perfect humidity level. 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: Always insert Boveda packs into a protective Boveda Fabric Holder before using in an instrument case. Boveda Fabric Holders are available separately & in Boveda Starter Kits. Remove the clear plastic overwrap before using. DO NOT cut or open the brown humidity packet. Slip the packet into the holder. Place in case and close the lid. BOVEDA DOES THE REST. When High-Absorbency Boveda 49% RH puffs up, it’s time to replace the pack. NEVER MIX the 49% HA with any other %RH. WHO IS HIGH-ABSORBENCY BOVEDA FOR: Musicians who live in year-round extreme humidity who struggle to maintain the right RH for instrument storage use Boveda HA 49 for acoustic & electric GUITARS, 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 cases. NO DAILY MAINTENANCE! WHY RISK A WARPED OR CRACKED INSTRUMENT OR MUSTY CASE?
