No rewetting! Protects fretted, bowed & woodwind instruments from humidity fluctuations. A Size 320 maintains the ideal humidity level for an instrument for months. NATURAL INGREDIENTS. Trusted by over 3 million people to protect & maintain items at the perfect humidity level. WE GUARANTEE QUALITY! - 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 display or utility 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 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: Use 1 Size 320 PER INSTRUMENT in a display case for up to 6 instruments. Remove the clear plastic overwrap before using. Do NOT open the brown humidity packet inside. Do NOT remove the Boveda pack from its brown cardboard box for use with instruments. Simply place the Boveda in your instrument display case and close the door. Or affix the pack to your case using a Boveda Mounting Plate (available separately). Replace this pack every 3 months. NEVER MIX the 49% with any other %RH. - WHO IS BOVEDA FOR: Boveda 49% RH is for acoustic & electric GUITAR players & musicians who play 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 display cases. NO DAILY MAINTENANCE! Don’t risk damaging an instrument by adding water to sponges and snakes & forgetting to refill them.

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 ### ⭐⭐⭐⭐⭐ Great product. *by J***S on April 2, 2025* Great product. Keeps those guitars from getting parched. Be aware that this particular unit is big and for guitar collection cases and not individual guitar cases. ### ⭐⭐⭐⭐⭐ Easy to use, work as advertised *by N***5 on March 4, 2025* Bought them to humidify a cabinet converted for ukulele storage. They work great, maintain promised humidity levels. ### ⭐⭐⭐⭐⭐ Used to store puerh teas, carries no odor. *by F***R on August 26, 2025* Unlike grains, seeds, coffee or mayonuaha, puerh tea is a living material. It ages and improves for years and even decades. If it is left in contact with the tiniest bit of odor, it will absorb it and return it all during drinking. Thankfully, the Boveda is absolutely odor-free and perfectly suitable for tea aging. This has been verified not just by me, but also by a whole community of tea collectors over the years. If you’re new to aging tea, keep reading. Green tea should be drunk within two months of opening. Any later and it develops harmful toxins. Oolongs are more processed and should be drunk within about a year or so. Oolongs do not usually develop toxins but do deteriorate and should be kept in sealed original packaging. Puerhs (especially sheng puerhs) and white teas are minimally processed, intentionally. They still contain live enzymes, live of bacteria and live yeasts. This is why some of the best stuff comes from forests. It also means that aging requires a certain humidity level. Bacteria and yeasts do not have legs. They do not spread under 71% relative humidity. Under this threshold, they will work in moderation and in sync with the enzymes. Above this threshold, they will spread and overpower the tea with earthy, woody, mushroomy and sometimes metallic or pungent aromas and flavors. Most people are into the lighter fruity and floral flavors that you only get under 71% relative humidity. So make sure you know what you are going for, if you’re using Boveda humidity packs to age your tea. Keep in mind that your cake or tong is probably around 50% rel. humidity by the time it reaches you. Its humidity will average out with this pack. You will be well under 71%. There’s really no difference between say 55% and 70% for ageing. All the enzymatic, bacterial and fungal processes probably work at a constant rate. 50% rel. humidity is probably too low and may halt aging altogether. The tea will still lose its youthful flowery tones, but without gaining the smooth and deep texture of aged tea. I use the 49% pack to bring down teas previously stored above 70%. It’s also important to always stay above 68°F (ideally 70-80°F), and absolutely imperative to avoid exposure to light. I use large steel canisters, which I thoroughly clean and bake in an oven at 500°F, before use. They come covered in oil residue from production that cannot be cleaned by household cleaning agents. This residue get burnt off together with its odor and easily wiped with a neutral cotton towel afterwards. I clean and wipe the silicone rubber seal ardently. My steel canisters are each filled densely with teas of similar character. They contain no paper other than production wrappers and no synthetic packaging. I store them in a warm bedroom without unpleasant smells. ## Frequently Bought Together - Boveda 49% Two-Way Humidity Control Pack for a Wood Instrument in a Display Case or Utility Case – Size 320 – Single – Moisture Absorber – Humidifier Pack – Individually Wrapped Hydration Packet - Boveda 72% Two-Way Humidity Control Packs For Wood Humidifier Boxes – Size 60 – 4 Pack – Moisture Absorbers – Humidifier Packs – Hydration Packets in Resealable Bag - Boveda 72% RH 2-Way Humidity Control – Restores & Maintains Humidity–All in One Solution for Humidification- Patented Technology for Humidity Control Convenient & Versatile - 10 Count 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.be/products/45509727-49-two-way-humidity-control-pack-for-a-wood-instrument](https://www.desertcart.be/products/45509727-49-two-way-humidity-control-pack-for-a-wood-instrument) --- *Product available on Desertcart Belgium* *Store origin: BE* *Last updated: 2026-04-23*
