The simple 2-way system is easy to use. All you have to do is put two gel bags in a fabric bag and hang the fabric bag in the sound hole of the guitar when it is in its box. Thereafter, the relative humidity will remain at ≈49%. The gel bags should not be activated - they are ready for use.
We recommend 49% RH for the cold Nordic climate.
