## Features

- WHY THIS BOVEDA: ORDER 2 STANDARD REPLACEMENT PACKS FOR A BOVEDA SMALL or DIRECTIONAL STARTER KIT or TO FILL A BOVEDA SINGLE or DOUBLE FABRIC HOLDER. (PLEASE NOTE - BOVEDA FABRIC HOLDERS ARE NOT INCLUDED WITH THIS ITEM). 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!
- 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.
- 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(s) into the holder(s). Place in case and close the lid. BOVEDA DOES THE REST. Replace every 3 months. Swap out Boveda when it becomes hard & crunchy. 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 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.

### ⭐⭐⭐⭐⭐ Easy way to maintain humidity
*by P***S on January 22, 2023*

I have been using these packets to maintain humidity for my wooden instruments for over 8 years now. They are the easiest and cleanest way to keep the humidity level up especially in our harsh Buffalo winters where our humidity indoors can be below 20%. Unlike other methods there is never a worry for the development of mold or mildew. They are also good at keeping humidity down in the summer however I do not find them to be as efficient doing so. When measured with several humidity gauges I find the packets to be within 10% of the numbers on the packets. Interesting note, the instructions state to discard when they become dry, however I have rejuvinated all of my dried packets by placing them in ziploc freezer bags with a drenched sponge. Over a day or so they will soften back up and work as well as when I first bought them.
