Information

HOW TO USE:

  1. Just slip unwrapped Boveda into the pouch(es) of its protective fabric holder.
  2. Place in case and close the lid. Always keep your case closed when using Boveda.

Always insert Boveda into a pouch of a Boveda Fabric Holder before placing in an instrument case. The fabric holder allows Boveda to last longer and work better and acts as a liquid barrier if a packet is accidentally punctured. 

DON'T:

  • Mix Boveda 49% RH High-Absorbency and Boveda 49% RH or different Boveda RH levels within the same instrument case
  • Use Boveda in the same case with other humidification products because they will fight against each other and reduce the efficiency of Boveda
