Komenuka is the Japanese name for rice bran, which forms the basis for these plant-based candles, made by a 100+ year old Japanese family company whose origin lies in the production of candles for Buddhist temples. Made from 100% rice bran wax, they burn cleaner and brighter than paraffin, beeswax, and soy wax candles. They’re further distinguished by their extremely long burn times: the Small size burns for 48 hours, the Medium size for 96 hours and the Large size for a whopping 120 hours. The soft dark ivory color is both natural and pleasing to the eye.
