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 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 - 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 for Music | Single Fabric Holder for 49% RH Boveda 2-Way Humidity Control | For Use with 1 Boveda Size 70 to Protect Smaller Wooden Instruments from Cracking and Warping --- ## 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.pt/products/25434022-49-two-way-humidity-control-packs-for-music-instruments-4](https://www.desertcart.pt/products/25434022-49-two-way-humidity-control-packs-for-music-instruments-4) --- *Product available on Desertcart Portugal* *Store origin: PT* *Last updated: 2026-06-08*
