Boveda B49-70-4P 2-Way Humidity Control - Refill 4-Pack

BOVEDA REFILLS

 

Only Boveda’s patented 2-way humidity control adds or removes moisture to balance fluctuating humidity during seasonal changes and travel to maintain the ideal humidity level in your guitar, violin, cello and other wood and wooden wind instrument cases.

 

This 4-pack will replenish your Boveda 2-way Humidifier so you can keep your instrument healthy and prevent warping, cracking, buzzing, shrinking, and expansion. 

How to use Boveda in your instrument case:

 

 

No maintenance for months! Initially, Boveda has some catch-up work to do, so your first Boveda won't last as long as subsequent ones. After your first set, Boveda will last 2-6 months depending on the time of year, your climate and your case. Replace when rigid.
