Follow strict moisture guidelines? Then package, store and transport your product with Boveda, the global leader in 2-way humidity control. Your product can sit in inventory, on a dock or on the shelf for months. Keep moisture-sensitive products safe from the dangers of humidity damage, such as over drying, degradation, flaking, clumping and mold. Packages include 10 Boveda Size 8s. 


Individual product dimensions: 2.75" x 2.5"

Prevents physical and chemical changes to moisture-sensitive materials, like foods, powders, capsules and archival and archeological materials. 

Stop fluctuating humidity levels from changing the look, aroma and taste of foods, medicines and health and beauty products. Or destroying archival materials, like photos and negatives.

Simply insert a Size 8 Boveda in with up to 1 oz of product, then factory seal or manually close the package. Boveda’s precise humidity control automatically restores and maintains humidity in any type of airtight container.

Patented technology uses all-natural salts and water in a leakproof vapor phase osmosis membrane to ensure a precise 49% Relative Humidity (RH).

Boveda is also available in other sizes and eight RH (RH: 32%, 58%, 62%, 65%, 69%, 72%, 75% and 84%) for all your packaging needs.

Long lasting—Provides humidity management for 6-9 months in an airtight package and 2-4 months in a container that’s frequently opened and closed. A simple touch test will let you know when it’s time to replace Boveda—it will feel crunchy and rigid.

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

    Not living up to the hype

    I purchased these to maintain a nice 49% humidity level in my guitar cases. Guitars should be kept around 40%-60% humidity levels. The house humidity level is around 65% and these have only dropped the level to 60% in 4 different cases with metering devices in each. I was hoping for a little better control factor than a 11% deviation from whats listed on the packet. I will edit this review if the packets dry out more and regulate the humidity better but currently that hasnt been the case.

    Perfect Fit for Baritone Ukulele Sound Hole

    I bought these along with a regular saddlebag for my Mitchell baritone ukulele. The standard 70 gram ones that usually go with the saddlebags (for guitars) were too large for my ukulele's sound hole. I need to measure the humidity to see if I need to add more humidifier packs to the saddlebag, but I was just happy it fit.
