Never leave the candle unattended. Keep away from children and animals. Regularly cut the drill bit to 5 or 6 mm and keep it at the correct height. Regularly recenter the bit. At the end of the first use, make sure that the liquid wax covers the entire surface of the candle by rotating it on itself. Extinguish the smoking candle (check the recommendations before relighting it). Do not place on a flammable or fragile surface. Do not let burn for more than three consecutive hours.
