Crafted with premium materials and meticulous attention to detail for long-lasting performance. - 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 | B0CX738PMD | | Best Sellers Rank | #409 in Musical Instruments ( See Top 100 in Musical Instruments ) #6 in Guitar Cleaning & Care Products | | Brand Name | Boveda | | Capacity | 60 Grams | | Color | Boveda brown | | Control Method | Touch | | Customer Reviews | 4.6 4.6 out of 5 stars (491) | | Included Components | (1) Single Fabric Holder (1) 49% RH High Absorbency Pack | | Item Dimensions D x W x H | 0.71"D x 7.01"W x 7.01"H | | Item Shape | Rectangular | | Manufacturer | Boveda | | Material | All-Natural Saltwater Humidfier Packets & Fabric Holder | | Model Name | Small Music Starter Kit - (3) Size 70 49% RH | | Model Number | Large Instrument Starter Kits | | Operation Mode | Automatic | | Other Special Features of the Product | Quiet | | Part Number | Large Instrument Starter Kits | | Power Source | Corded Electric | | Room Type | Bedroom, Living Room | | Runtime | 24 hours | | Smart Home Compatibility | Not Smart Home Compatible | | UPC | 850023359728 | | Unit Count | 1.0 Count | ## Product Details - **Brand:** Boveda - **Capacity:** 2.11 ounces - **Color:** Boveda brown - **Operation Mode:** Automatic - **Special Feature:** Quiet ## Images ![49% Guitar Humidifier Kit, 3 Packs + 2 Holders – Large Instruments - Image 1](https://m.media-amazon.com/images/I/81Jd2f32BVL.jpg) ## Available Options This product comes in different **Size** options. ## 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. ## Frequently Bought Together - Boveda Music Large Starter Kit - (3) 49% RH Standard Boveda - Ideal Two-Way Humidty Control for MOST CLIMATES - For Guitars & Other Large Wooden Instruments - Boveda 49% Two-Way Humidity Control Packs for Music Instruments – 4 Pack – Standard Size – Prevents Warping & Cracking for Wooden Instruments– Humidifier Packs for Instrument Cases – Resealable Bag --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.jp/products/615445520-49-guitar-humidifier-kit-3-packs-2-holders-large-instruments](https://www.desertcart.jp/products/615445520-49-guitar-humidifier-kit-3-packs-2-holders-large-instruments) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-08-05*
