## Description

desertcart.com: Boveda 49% Two-Way Humidity Control Pack for a Wood Instrument in a Display Case or Utility Case – Size 320 – Single – Moisture Absorber – Humidifier Pack – Individually Wrapped Hydration Packet : Musical Instruments

Review: Perfect for guitars - I have been using the Boveda 49% Humidity Packs for years in all of my acoustic and electric guitars. They are super easy to use. There is no muss, no fuss as the gel liquid is in sealed the packets. I live in the NE so with the heat on in the winter it can be very dry (low humidity) and without a/c the summers get pretty sticky (high humidity). These packs do a pretty good job regulating the humidity in the case. I use the Boveda Double holders which holds two humidity packs and put one double holder over the strings and hang it into the sound hole of my acoustics and one double holder with two packs under the headstock. The inside of the case stays between 45% and 55% which is ideal. I do the same for my electrics but I only use one double under the headstock. I found this is enough to keep the fretboard hydrated and prevent fret sprout. I find that I am getting 8-12 months of use out of the packs using them the way I do once they are opened. I buy in bulk and store the unused, unopened packets in heavy duty zip lock bags. Never had a problem doing this even if they are stored for a year.
Review: Great Humidifier for Ukuleles - I use 49% RH Boveda Packs to keep my wooden tenor ukuleles humidified when the RH gets below 42% in the Winter. Especially when the furnace is running. The humidity often gets below 18% RH here in Wisconsin. They are great. Absorb moisture and releases it to keep a pretty constant level in my ukulele cases. Some cases require that I place a pack in the body of the uke, others that are more airtight, I keep one above the heel. I also place an older, rejuvenated pack under the headstock. I strongly recommend that you use these in a Boveda Sleeve. It prevents the pack from coming in contact with the finish or wood of the instrument. In the very remote chance that a pack gets damp it also protects the wood. (Out of 400+ packs over the years, I've only had one get a damp spot. Back when they used a crystalline absorption material that I squeezed too hard and it punctured the inner envelope. They now use a plant-based material.) The sleeve also helps provide a more uniform release of moisture. Smaller ukes may require a different placement in the case. Larger baris may need two. Boveda recommends hanging two packs over the strings and into the body. With a third in the headstock part of the case. Great product. Low maintenance.

## Features

- 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!
- 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?

## 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.
