With D'Addario's two-way humidification bulk refill pack you get twelve brand new packets specifically designed for the D'Addario Two-Way Humidification System, enough to refresh your entire Humidification set.
The Two-Way Humidification System is a maintenance-free two-way humidity control system that is perfect for your electric, acoustic, or classical guitar.
(The Two-Way Humidification System was formerly known as the Planet Waves Humidipak.)
To use one or more packets, simply open the foil-sealed pack by pulling gently on the sticky-tape seals. Remove the number of packets you need, then reseal the foil pack by pressing the sticky-tape back into place. The remaining packets will be preserved until you need them.
Once activated (by removing the packet from the foil-sealed package), this unique two-way humidity control system completely eliminates the guesswork and anxiety from maintaining your instrument's proper humidity level.
This package includes twenty-four replacement gel-packs, which are meant for use with the Two-Way Humidification System pouches (sold separately as a starter kit).
When used as a set, the Two-Way Humidification System has the ability to provide 27 grams of water, that's enough moisture to completely restore an extremely dry guitar to 45% RH without the risk of over-hydration. At the same time the standard packet can absorb more than 11 grams of water, enough to completely restore a very wet instrument to 45% RH.
No water. No drips. No mess. No fuss.
Eliminates all guesswork.
Replace your gel pack when it is stiff and if difficult to press your fingers into. A typical gel pack, once activated, should last two to three months (depending on your use and environment).
