Humidity control is vital in maintaining your acoustic guitar.
If the guitar is exposed to too much humidity the top can swell and raise the bridge (higher action)
If it dries out the top can start to sink.
Both of which can cause permanent damage if the top wood splits.

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.
Size Large is for fretted/bowed wood instruments (acoustic guitars and more). Includes: 4 Size 70 Boveda 49% RH and 2 double (2-pouch) fabric holders: 12.5" x 4.25" (unfolded); 6.625" x 4.25" (folded)
Always insert Boveda into a pouch of a Boveda fabric holder before placing in an instrument case. Do not mix different Boveda RH levels within the same instrument case. And do not use Boveda in the same case with other humidification products because they will fight against each other and reduce the efficiency of Boveda.
