Having been in the industry for more than 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 & 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 the Boveda packs into the fabric holders included in this Large Starter Kit, position them in your case & forget about the packs. Refill after 3 months. USE THE BOVEDA HIGH ABSORBENCY LARGE STARTER KIT in EXTREME HUMIDITY CLIMATES ONLY (60%+). Absorbs 3X the amount of moisture as Boveda 49% Standard in an instrument case to maintain the right humidity for: a GUITAR, including acoustic, guitarrón, hollow-body, nylon string, semi-hollow body, electric or bass; LARGE STRING, including cello/violoncello, double bass/upright bass & hollow-body bass; & LARGE WOODWIND, including bass clarinet & bassoon.

Review: Amazing - Perfect for my violin humidity control, realy works Review: Still working after 6 months of use - Works great, I am at 6 months including end of summer, fall and now winter in the Toronto area and I am still keeping my humidity on target. I should mention that I am disciplined in that I close my case as soon as I take the guitar out to keep a steady humidity in my hard shell case. I would give it more stars as it surpassed the predicted duration of effectiveness. ## Features - 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 more than 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 a Boveda pack into the included protective Boveda Fabric Holder before using in an instrument case. Remove the Boveda from the plastic bag 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. Replace every 3 months. NEVER MIX the 49% with any other %RH. - WHO IS THIS LARGE BOVEDA KIT FOR: Players of acoustic guitar; hollow-body guitar; nylon string guitar; semi-hollow body guitar; guitarrón hollow-body bass; cello/violoncello; double bass/upright bass; bass clarinet; or bassoon. Professional musicians; band & orchestra leaders; instrument techs; music teachers; hobbyists & student musicians use Boveda packs for easy & precise humidity management for instrument storage. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0CX7C3NQ5 | | Brand | Boveda | | Brand Name | Boveda | | Capacity | 60 Grams | | Color | Boveda brown | | Colour | Boveda brown | | Control Method | Touch | | Customer Reviews | 4.5 out of 5 stars 294 Reviews | | Included Components | (1) Double Fabric Holder (1) Single Fabric Holder (3) 49% RH High Absorbency Packs | | Item Shape | Rectangular | | Item height | 6.5 inches | | Manufacturer | Boveda | | Material | All-Natural Saltwater Humidfier Packets & Fabric Holder | | Model Name | Small Music Starter Kit - (3) Size 70 High Absorbency 49% RH | | Model Number | Large Instrument Starter Kits | | Operation Mode | Impeller | | Operation mode | Impeller | | Other Special Features of the Product | Humidistat | | Power Source | Battery Powered | | Room Type | Living Room | | Room type | Living Room | | Runtime | 24 hours | | Special features | Humidistat | | UPC | 850023359742 | | Unit Count | 1.0 Count | ## Product Details - **Brand:** Boveda - **Special Feature:** Humidistat - **Color:** Boveda brown - **Room Type:** Office, Bedroom, Living Room - **Model Name:** Small Music Starter Kit - (3) Size 70 High Absorbency 49% RH ## Images ![Music HIGH ABSORBENCY Large Starter Kit - (2) 49% RH High Absorbency Boveda - Ideal Two-Way Humidity Control for EXTREME HUMIDITY CLIMATES ONLY - For Guitars & Other Large Wooden Instruments - Image 1](https://m.media-amazon.com/images/I/819ck3+fQyL.jpg) ## 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. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Amazing *by R***A on 12 November 2024* Perfect for my violin humidity control, realy works ### ⭐⭐⭐⭐⭐ Still working after 6 months of use *by J***Y on 15 January 2026* Works great, I am at 6 months including end of summer, fall and now winter in the Toronto area and I am still keeping my humidity on target.
