Kai-un-koh is one of the finest and purest quality scents you will find anywhere. A high-quality, high-resin Aloeswood is the primary ingredient here. This precious, natural, healing substance creates an aroma that is majestically deep and ancient. You will find the deep, inspiring, calming aroma, in each (very thick) Kai-Un-Koh stick, to be absolutely STUNNING and unforgettable.
