Caution!!! Discard using candle when wax is at 1/4 inch. If you burn to the bottom the wax can suction under the wick tabs and cause high flames. Some of these candles contain herbs and must not be left unattended or out of sight. Dry herbs moving near a flame could possibly light causing smoke or high flames, please be aware of this. Always use caution with open flame candles! Place in a safe location, keep supervised at all times away from children & pets. You are agreeing to these terms if you purchase our candles.
