D'Addario Planet Waves Humidipak Restore System for Extreme Dryness
The Humidipak Restore System allows your instrument and case that have previously not been humidified or are in a known dry condition to return to the ideal humidity level without danger of over humidification. Using Boveda's patented two-way humidity control technology, this automatically adds moisture at an accelerated yet safe rate to re-establish the ideal humidity level inside your instrument case, eliminating the guesswork and anxiety of revitalizing your instrument. Contains 3 packets: 1 for the headstock and 2 for the soundhole. Once at 45-55% relative humidity, the standard Humidipak packets should be used (#PWPAK3).
