I only trust Boveda for cigar humidity control. I use these 58%, 62%, 65%, and 69%

Sind super, halten ewig

This review and rating is strictly for using these in a guitar case. I use Boveda packs in my humidor and they work great. A large pack will last me at least a month. This was the first year I decided to try them in my daughter’s guitar cases. I did so because I was tired of the constant refilling and risk of leaks with refillable guitar case humidifiers. The Boveda packs lasted about two weeks before they dried out. They do work with guitar cases but costs mount quickly due to the more frequent replacements required. I was going to purchase a second box of Boveda packs but opted instead to re-purchase the refillable guitar humidifiers. I need a more cost effective option to last all winter.

Increase humidity

I purchased these to restore and maintain a nice level of moisture for my 💐 🌹, and don't get me wrong these work but the 62% Boveda packs are the level of moisture I was looking for. Be sure to read what the numbers on the front of the pack are specifically for.
