Are you using enough Boveda packets?
You can add as many additional packs to Boveda Holders in your case as you would like or as climate dictates.
While we recommend a minimum number of Boveda to store with each size instrument, you can add as many additional packs to Boveda Holders in your case as you would like or as climate dictates.
In extreme climates (below 40% humidity or above 60% humidity), you can add more Boveda to your case. Extra Boveda Holders are available here.
