I use two airtight Tupperware boxes about the size of a shoebox, with a big 320 gram Boveda 65% in each with a cheap Govee hygrometer shoved in the front. Conventional wisdom says not to use the airtight Tupperware because the sticks need gentle air circulation. Mine are packed in pretty full and airflow is further inhibited by placing groups of cigars in big zip lock bags for some smidge of organization. Being airtight, it will often get slightly over-humidified, as well, sometimes for extended periods of time. All of that being said, I’ve had zero issues with the setup. The first Boveda I put in is still completely juicy over 2 years later, too.
