Boveda49% Two-Way Humidity Control Packs for Music Bows & Small Woodwinds – Size 8 – 10 Pack – Moisture Absorbers for Small Instrument Cases – Humidifier Packs – Hydration Packets in Resealable Bag

Purchased second unit, works great

Excellent product. Lines up with my meter and provides great results.

I recently started using Boveda moisture packs to help regulate the humidity in my cigar humidor, and I have to say, they're pretty amazing. The packs are designed to maintain a specific level of humidity, which is essential for preserving the flavor and quality of cigars.What I love most about these moisture packs is how easy they are to use. All I had to do was simply place them in my humidor, and they started working immediately. The packs are also long-lasting, so I don't have to worry about replacing them frequently.While they are a bit expensive, I think they are well worth the investment. The quality of my cigars has improved significantly since using these moisture packs, and I know that they will last a long time, which ultimately saves me money in the long run.Overall, I highly recommend Boveda moisture packs to anyone who wants to ensure the best possible quality for their cigars or other items that require humidity control. Yes, they are a bit expensive, but the benefits they provide are definitely worth the cost.

The Boveda system, also used by d'Addario, keeps my guitars happy year round. It works very well. Since the plackets are throwaway, it's more expensive than systems (like Oasis) that you refill, but is very convenient.This item is 10 tiny packs. The low price should have tipped me off, but I was surprised. "Size 8" doesn't tell you anything, but it would take several of them to add up to one of the larger packs, of which I use 2 or 3 in a guitar case. These small packs would be fine for a much smaller instrument than a guitar, like a flute.

Nice wooden musical instruments (both big and small) can crack and split if not kept within their climate tolerances. These 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.

They work😁

Fantastic for maintaining reloading gunpowder! It has been determined that humidity plays a major factor in both burn rate and powder weight. Powder comes from the factory around 50 -55% RH. An open can will stabilize to the ambient RH. Here in Wyoming one of my open cans was 30% RH which means is burns faster (hotter) and weighs less on the scale. So you charge more/ hotter powder per a given charge weight than factory. Studies have shown this can effect velocity (which also mean pressure) up to 200 fps! 😳By suspending a 49% Boveda cigar humidor pack in the can ,one can bring the RH up to the factory level. The Maestro bluetooth sensor allows you to check and monitor the RH in a closed can. I made a small sack out of nylon stocking type material to keep kernels out of the sensor. This Also allows for a convenient string attachment point lowering into the kid and retrieving.

I averaged.I used these in a sealed container and sure enough they held the exact humidity value of 58%. The packets had 49% but were 58%. I had Amazon replace them... same thing.They work great but their manufacturing accuracy failed badly.
