Boveda 49% Guitar Humidifier Refills, 4-Pack - Large Instrument Cases

I use these in my guitar case for my Martin guitar. Never had a problem with going from Iowa to Florida every year with my Martin. Always stays at the perfect humidity.

Excellent. Does what they’re supposed to do. Fits perfectly into my D'Addario pouches.

Love em!

They work on all my acoustic guitars. Peach of mind for a few bucks and last a long time.

+ They make a difference in humidity levels. + They slow down how quickly the humidity changes. + Easy. Put em in and forget about em. + They work to keep humidity at a stable level so you can't over-humidify (which is worse than dry). + They last pretty long. Around 5 months for us. + They don't leak. - While they do work, they can't really keep the humidity level to 49% in our cases. We use a room humidifier and our winter RH is right around 35%. Inside our cases it's around 40%. -More garbage for the landfill compared to reusable sponge type humidifiers.

Trust the teacher, trust the brand, no deficit noticed.

Boveda makes the best quality humidification pack for guitars

When I needed to replace these quickly, I was happy to find them on Amazon. I have these for several instruments. They seem to work well and don't leak if used as directed.

Funcionan en el clima seco de madrid tal y como describe el fabricante. En los momento de más sequedad atmosférica (20%+), en una guitarra que estaba una funda no rigida, he metido 2 dobles fundas (4 bóvedas), pero era de esperar. También subrayo que duran mucho: de momento, y en estas condiciones, han pasado meses y ayer acabo de notar los primeros cristales 'duros'.

Nice kit and affordable compared to other brands.

👌

Product arrived and each packet had a moisture collected in the bottom left of the packet. Not sure if this is how the product is meant to arrive.

indispansable pour conserver les anches à la bonne hygrométrie
