  • One (1) Single (1-Pouch) Boveda Holder
  • Three (3) Boveda Refill Packets
  • Step-by-Step Instructions

HOW TO USE:

BEFORE USING BOVEDA:

  • ALWAYS insert Boveda into a holder before using in your instrument case. The holder acts as a liquid barrier if a packet is accidentally punctured and extends the life of your Boveda packets. The patented interior material allows water vapor to pass through to your instrument. The exterior is soft, like a polishing cloth, so it doesn’t scratch your instrument. 
  • DO NOT mix different Boveda RH levels including Boveda B49HA within the same instrument case.  
  • DO NOT use other humidification products with Boveda in the same case because they will fight against each other and reduce the efficiency of Boveda.

STEP-BY-STEP INSTRUCTIONS:
  1. Remove the clear overwrap from the packet. (DO NOT OPEN the Boveda itself.)
  2. Insert one (1) unwrapped Boveda into each pouch of each holder.
  3. Place in the case anywhere that allows for airflow and prevents puncture when you close the case.
  4. Close the case's lid. Always keep your instrument case closed when using Boveda.

PLACEMENT IDEAS:

Double holder:
  • Into the sound hole
  • Over the strings
  • ­Open area in the case

Single holder:
  • Under the neck or headstock
  • On the strings
  • Under the tailpiece
  • Open area in the case

PACKAGING:

Each Boveda in these kits is individually overwrapped. An unopened Boveda is good for up to two (2) years.

LIFESPAN:

Replace Boveda 2-way humidity packets every three (3) months.

ACCURACY:

Achieves and maintains a constant relative humidity (RH) range between 40% and 60%, the industry standard for wooden instruments.

INGREDIENTS:

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

    Works great!!

    Great product! Easy to use, no mess, way better than traditional water/sponge humidifiers. Works great with my Martin OMC and my Fender Acoustasonic! Ordering again soon.

    New Guitar clearly needed TLC

    I am a beginner and bought a new guitar for my lessons. I got a Martin Road Series 000-13E Retro with a spruce top and solid black walnut back & sides. I did research and was told by many folks to get a humidity solution ASAP especially since PA is going through a very cold winter.

    I've owned the guitar for exactly one week. I placed the Boveda pack in my hard case about three days ago.

    Much to my surprise, when I opened the case to practice this morning, an overwhelming smell of fine wood filled the air. I took a deep inhale at the sound hole and I cannot tell you how amazing it smells. Also, after just three days of getting humidity....the guitar's sound has GREATLY improved. Each chord has a very full sound and amazing sustain. I never would have thought humidity would have such an immediate and massive impact on the sound and playability of the guitar. I will never be without these packets.

    Helps a lot! One small question

    My hometown has gone up and down from 50F to 10F in the last weeks and my semi-hollow is holding up very well!! But I do realize I need to have a humidifier in my room anyway as the humidity drops to 15-20 otherwise, but this is ok. But, I'm now going to be away for 6 days and am a bit concerned what will happen when my room humidifier runs out of water; should I add a bunch of guitar humidifiers in the case along with the Boveda packs, or is this overkill?

    High absorption

    The 49HA High Absorption packets are the only product that I have found on the market that work effectively in my year-round humid climate.
