If they are an essential component of the system, why are they $10 a pop. The price is near double their competitors who sell both together at near half the price. Caveat emptor. Review: Humidity pack holder - These humidity packs work great in my guitars. Delivery was excellent. ## Features - ORDER AN EXTRA BOVEDA FABRIC HOLDER to use with Boveda, the global leader in 2-way humidity control for wooden instruments - DOUBLE-SLEEVE SADDLEBAG holds two (2) 49% RH Boveda Size 70 (sold separately) to precisely achieve and maintain between 45% and 55% RH—the safe zone for wood instruments.

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 ### ⭐⭐⭐⭐⭐ Way too expensive! *by M***Y on September 10, 2022* I like the idea of protection of my instruments, but what I don’t understand is why these are sold separately from the humidity control packs. If they are an essential component of the system, why are they $10 a pop. The price is near double their competitors who sell both together at near half the price. Caveat emptor. ### ⭐⭐⭐⭐⭐ Humidity pack holder *by R***. on June 12, 2025* These humidity packs work great in my guitars. Delivery was excellent. ### ⭐⭐⭐⭐⭐ Thin and light weight *by C***I on February 16, 2021* Must have for expensive guitars, these hold humid pacs perfectly, the packs need to be replaced every 2 months but you only need them in the winter. Low humidity is the Bane of acoustic guitars. ## Frequently Bought Together - Boveda for Music | Double-Sleeve Fabric Holder for 49% RH Boveda 2-Way Humidity Control | For Use with 2 Boveda Size 70 to Protect Large Instruments from Cracking/Warping - 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.sc/products/244511537-double-sleeve-fabric-holder-for-49-rh-2-way-humidity](https://www.desertcart.sc/products/244511537-double-sleeve-fabric-holder-for-49-rh-2-way-humidity) --- *Product available on Desertcart Seychelles* *Store origin: SC* *Last updated: 2026-08-05*
