They are super easy to use. There is no muss, no fuss as the gel liquid is in sealed the packets. I live in the NE so with the heat on in the winter it can be very dry (low humidity) and without a/c the summers get pretty sticky (high humidity). These packs do a pretty good job regulating the humidity in the case. I use the Boveda Double holders which holds two humidity packs and put one double holder over the strings and hang it into the sound hole of my acoustics and one double holder with two packs under the headstock. The inside of the case stays between 45% and 55% which is ideal. I do the same for my electrics but I only use one double under the headstock. I found this is enough to keep the fretboard hydrated and prevent fret sprout. I find that I am getting 8-12 months of use out of the packs using them the way I do once they are opened. I buy in bulk and store the unused, unopened packets in heavy duty zip lock bags. Never had a problem doing this even if they are stored for a year. Review: Good product - I use em in my guitars.

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 ### ⭐⭐⭐⭐⭐ Perfect for guitars *by D***S on August 24, 2022* I have been using the Boveda 49% Humidity Packs for years in all of my acoustic and electric guitars.

They work great ### ⭐⭐⭐⭐⭐ Must have *by D***N on March 27, 2023* Those who own sensitive acoustic guitars that need PROPER HUMIDITY KEPT, will want these. I used to use the sponge humidifiers, but that caused my Takamine 12 string to over humidify and swell at the bridge. Since these do both humidify and dehumidify, they actually fixed my swelling issue with my 12 string! My Martin would suck up all the water in the sponge humidifier within a week during the winter months. These last a month or two for me before I need to change them for new ones. I think the 12 pack is a great value and these packets are a must have for my acoustic guitars. Nake humidity maintenance so much easier. ## Frequently Bought Together - Boveda 49% Two-Way Humidity Control Replacement Packs for Boveda Starter Kits for Music – 12 Pack – Moisture Absorbers for Instrument Cases – Humidifier Packs – Individually Wrapped Hydration Packets - 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 Double-Sleeve Fabric Holder for 49% RH | 2-Way Humidity Control for Large Instruments --- ## 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/11668034-boveda-49-two-way-humidity-control-packs-for-wooden-instruments](https://www.desertcart.jp/products/11668034-boveda-49-two-way-humidity-control-packs-for-wooden-instruments) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-04-23*
