How many Boveda packets do I need for a ukulele or small instrument?
Use a minimum of one (1) Boveda refill packet in a Boveda Holder for ukulele and small wooden instrument storage.
In extreme climates (below 40% humidity or above 60% humidity), you can add more Boveda to your case.( link to B49 refills page).
Remember to ALWAYS use any additional Boveda with a Boveda Holder in your instrument case.
