NitriBurn Candles are made using the finest ingredients - 100% organic unbleached natural cotton, beeswax and impregnated with natural essential oils such as tea tree, lavender and sandalwood. Just Ear Candles are approximately 24 cm long (9 ½ inches). The entire range of Just Ear Candles contains a small filter embedded within the body of the candle which prevents backflow of debris into the ear. Marked towards the bottom of the ear candle is a line which indicates the "maximum burn" limit of the candle. The approximate burn time of the candle is between 5 and 7 minutes. A full set of instructions is provided with every order; we recommend that ear candles are only used with the supervision of another competent person. REMEMBER, IF IN DOUBT, ALWAYS CONTACT YOUR GP. DO NOT USE ON CHILDREN
