Your Kanile’a ’Ukulele is constructed from solid wood that was carefully dried and seasoned. Solid wood will absorb moisture in wet climates and give off moisture in dry climates. If you live in a desert, high mountain, or cold winter region, you will experience dry weather from time to time which could crack your ‘ukulele. This is especially true during the winter when your heaters are being used. If not taken care of properly the damage can be very serious and is not covered by this limited warranty. Cracking can easily be prevented by storing your ‘ukulele in its case and by using a sound hole humidifier.
