Replacement 72% Boveda Humidity Packs for Reed Cases - 1 Pack
 
Replace the humidity pack in your reed case when the existing humidity pack gets hard and "crusty." Simply remove the old one from the reed case lid and slip the new pack in, then you're ready to go! If you live in an extremely humid climate and are experiencing mold on your reeds, consider Boveda's lower-level humidity packs, such as the 62% or 58%.
