Fed up with adding water to your instrument? Toss the sponges, snakes and soap dishes. Just load these humidity packs into their fabric holders then slip them in your guitar or instrument case. That’s it!

For months, Boveda will automatically create the perfect humidity balance for a guitar or other wood instrument—whatever its surroundings call for. And protect against humidity fluctuations that can damage an instrument, affect its sound and playability and cost you money (and time) at the repair shop.

Fight the humidity battle with this all-in-one kit, which includes:

Two (2) Double (2-Pouch) Fabric Holders:

  • The patented interior material allows water vapor to pass through to instrument.
  • Give added protection by extending the life of the Boveda.
  • The exterior is soft fabric, so it doesn’t scratch your instrument.

Four (4) 49% RH Standard:

  • Keeps a wood instrument in the safe zone to prevent cracking, warping and other costly repairs.

Step-by-Step Instructions:

  • Learn how to position the holders and maintain your instrument with Boveda.

This kit is for storing one:

  • Acoustic guitar
  • Hollow-body guitar
  • Nylon string guitar
  • Semi-hollow body guitar
  • Guitarrón
  • Hollow-body bass
  • Cello/ violoncello
  • Double bass/upright bass
  • Bass clarinet
  • Bassoon



  1. Remove Boveda's plastic wrapper. (Do not open the Boveda itself.)
  2. Insert each unwrapped Boveda into a pouch of its protective fabric holder.
  3. Place in the case anywhere that allows for airflow and prevents puncture when you close the case:
    - Under the neck or headstock
    - On the strings
    - Drape over the strings into the sound hole
  4. Close the case's lid. Always keep your case closed when using Boveda.

Always insert Boveda into a pouch of a Boveda fabric holder before placing in an instrument case. The fabric holder allows Boveda to last longer and work better and acts as a liquid barrier if a packet is accidentally punctured. 

Do not mix different Boveda RH levels within the same instrument case. And do not use Boveda in the same case with other humidification products because they will fight against each other and reduce the efficiency of Boveda.

Use one (1) Large Starter Kit with four (4) Boveda 49% RH Standard (included).

Each Boveda in the Large Starter Kit is individually overwrapped. 

Boveda will last 2-6 months depending on the time of year, your climate and your case.
Unopened package: Up to two (2) years

Do the touch test. Order replacement packs here BEFORE Boveda is totally rigid to avoid a lapse in humidity protection for your instrument.
Boveda is still working if you feel: 
• Hardening at its corners
• Soft spots among some hard areas
Boveda is expired if: 
• The entire pack feels rock solid all the way through 

Achieves and maintains a constant relative humidity (RH) range between 45% and 55%.

Food-grade salt, purified water and a food-grade thickening agent sealed inside a leakproof membrane.

    Excellents produits

    J’ai acheté en ligne ces produits pour humidifier mes clarinettes. Le résultat est surprenant, mes clarinettes sont toujours à la bonne humidité et en plus cela protège des risques de fissures dans le bois.

    Appears to work.

    I've been using Boveda for about a month now and it appears to work as advertised. Guitar was re-hydrated and Boveda is keeping it in the proper humidity range while in the case.
