## Features

- WHY THIS BOVEDA: 4 STANDARD REPLACEMENT PACKS FOR BOVEDA STARTER KITS—SMALL, LARGE & DIRECTIONAL & TO FILL BOVEDA SINGLE & DOUBLE FABRIC HOLDERS. Protects fretted, bowed & woodwind instruments from humidity fluctuations. Maintains the ideal humidity level in an instrument case. 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 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.
- 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 for instrument storage. 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?

## Questions & Answers

**Q: Do I have to use a fabric holder with Boveda in an instrument case?**
A: YES! Always insert Boveda into a Boveda Fabric Holder before placing it in an instrument case. The fabric holder extends the life of Boveda plus acts as a liquid barrier if a pack is accidentally punctured.

**Q: Do I tear open the brown Boveda packet?**
A: NO!!! DO NOT OPEN the brown packet itself. If your Boveda arrived individually wrapped in cellophane, remove that plastic overwrap before slipping the humidity control pack into a fabric holder.

**Q: Should I use a sponge or snake with Boveda?**
A: No, do not use Boveda in the same instrument case with other humidification products, as this will reduce the Boveda’s efficiency. Ditch the sponges and hoses. No more rewetting— Boveda works automatically to balance the humidity in your case!

**Q: I live in a really humid place, so do I need Boveda in my instrument case?**
A: Yes! Boveda makes a High-Absorbency pack to protect wood instruments in extreme humidity, prevent warping and curb humidity fluctuations when you’re in a dry environment, like an airplane or air-conditioned venue.

**Q: What’s the difference between the Large and Small Starter Kits?**
A: The Large Starter Kit is the right Boveda for an acoustic guitar, large woodwind or large bowed or fretted instrument. Choose a Small Starter Kit to use Boveda with an electric guitar or bass, small woodwind or small bowed or fretted instrument.
