## Description

Review: Well worth it - These actually work really well. Definitely worth the purchase.
Review: Way too expensive! - 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.

## Questions & Answers

**Q: Do I have to use a fabric holder with Boveda in an instrument case?**
A: YES! 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.

### ⭐⭐⭐⭐⭐ Well worth it
*by D***N on October 22, 2025*

These actually work really well. Definitely worth the purchase.

### ⭐⭐⭐⭐⭐ 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.

### ⭐⭐⭐⭐⭐ Humidifies and Dehumidifies - perfect for small wooden musical instruments
*by A***L on August 17, 2024*

Nice wooden musical instruments (both big and small) can crack and split if not kept within their climate tolerances. These pouches are for the small packets (size 8) used for small instruments like ukuleles, mandolins, etc. The packets will both absorb or disburse moisture into the air around the instrument to maintain a specific level of humidity. They are manufactured for various levels of humidity so be sure to buy the ones that fit your need. Order the pouch and the packets to use together (don't use the packets without the pouch!) I like them so much, I gave my brother pouches and packets for his ukuleles and guitars as a gift.
