## 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 case?' Boveda's founders and 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—no more mustiness in your instrument case. Just slip a Boveda into a Fabric Holder (available separately), position it in your case & forget about the pack until it starts to get hard. Once it does, just switch it out with a replacement pack. (This multi-pack of Boveda 49 RH Standard contains 4 replacement humidity control packs in a reclosable bag.) Each 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 STANDARD HUMIDIFIER/DEHUMIDIFIER PACKS in an instrument 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. Subscribe & Save to get Boveda replacement packs sent to you automatically. Proudly Made in the U.S.A.

Review: 👌
Review: きっちり湿度をコントロールしたければBoverda一択だ．一見高い商品だが，予想よりもちがよい．また，湿度を保つケースに入れるより小回りが聞き，コスパはそれよりは良い．アマゾンで在庫切れになることがあり，その点は残念だ．特に冬場は湿度管理をしたい楽器が多く，必需品となっている．他の湿度を保つと言っている商品とは雲泥の差で優れている商品だ．お勧め．

## 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.
- 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 a pack from the resealable bag. 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. You'll know it's time to 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.

冬の暖房下、アコギの乾燥から逆反りで困っていて、一月ほど指板と弦の間に２つ挟んで保管したら、ネックガ良い感じに戻りました。ナットやサドルやトラスロッドをいじる前にまずは、適切な湿度調整が必要だと実感。良いです。
