Prevents warping instruments & the "musties" in your case. Protects fretted, bowed & woodwind instruments from humidity fluctuations to maintain ideal humidity in an instrument case. For use in Boveda Small or Directional Starter Kit or Single Fabric Holder. NATURAL INGREDIENTS. WE GUARANTEE QUALITY! - HOW HIGH-ABSORBENCY BOVEDA WORKS FOR MUSICAL INSTRUMENTS: ABSORBS 3X MORE MOISTURE than Boveda 49% RH! Stabilizes the humidity within the ideal range—45–55% RH, even in extreme humidity. 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: Trusted by over 3 million people to protect & maintain items at the perfect humidity level. 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 into the holder. Place in case and close the lid. BOVEDA DOES THE REST. When High-Absorbency Boveda 49% RH puffs up, it’s time to replace the pack. NEVER MIX the 49% HA with any other %RH. - WHO IS HIGH-ABSORBENCY BOVEDA FOR: Musicians who live in year-round extreme humidity who struggle to maintain the right RH for instrument storage use Boveda HA 49 for acoustic & electric GUITARS, 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 cases. NO DAILY MAINTENANCE! WHY RISK A WARPED OR CRACKED INSTRUMENT OR MUSTY CASE? ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07WQHX64Q | | Best Sellers Rank | #6,545 in Musical Instruments ( See Top 100 in Musical Instruments ) #85 in Guitar Cleaning & Care Products #512 in Humidifier Accessories | | Brand | Boveda | | Color | brown | | Color Name | brown | | Customer Reviews | 4.5 4.5 out of 5 stars (167) | | Date First Available | November 2, 2022 | | Included Components | 1 Humidity Control Packet - Overwrapped in Plastic (not resealable) | | Item Weight | 1.13 ounces | | Item model number | B49HA-40-OWB | | Manufacturer | Boveda | | Material Type | Plastic | | Model Name | 49% RH, Size 40, 1 Count, Humidity Control Packets | | Operation Mode | Automatic | | Product Dimensions | 5.25 x 0.25 x 3.5 inches | | Room Type | Add Boveda to Airtight Container, Glass Jar, Storage Bags and More to Maintain Humidity | | Shape | Rectangular | | Size | 49% Music - 1 Pack High Absorbency | | Special Feature | Two-Way Humidity Control | Safe to Touch items | Adds/Removes Moisture | Preserves Aroma, Flavor & Freshness | Long Term & Short Term Storage | Replace Every 3 Months | Protect Up To 1 lb (450 Grams) | | UPC | 852715006033 | | Unit Count | 1.0 Count | ## Product Details - **Brand:** Boveda - **Capacity:** 40 Grams - **Color:** brown - **Operation Mode:** Automatic ## Images ![High-Absorbency 49% Two-Way Humidity Control Pack for Music Instruments in Extreme Humidity – Single – Size 40 – Prevents Warping & Cracking of Wooden Instruments – Individually Wrapped - Image 1](https://m.media-amazon.com/images/I/51dZ71eIb0L.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. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Work well in my ukulele case *by J***G on March 11, 2026* Work well in my ukulele case ### ⭐⭐⭐⭐⭐ Would Recommend to Anyone *by S***. on October 31, 2025* I have used these for a few years now and they work extremely well.
