100% Hand made from unrefined beeswax and unbleached cotton fabric. All natural means there will be variations in color, texture and length. These candles will leave a powdery residue in the tip of the candle, not to be confused with yeast. Beeswax releases negative ions, burns clean and helps aid the body in softening ear pain and excess wax in the ear.
