Outdoor Use Only (if you choose to use indoor that is up to your discretion) We use natural pure soy wax to fill this rustic wooden log. It is then topped with Himalayan Salt which will sink and melt as you burn. The long wooden crackling wick is what makes our candles unique. 5.5 inches W x 18 inches L x 2.5 inches H is the approx size of each candle Once the candle has burned, simply wash out with hot water and soap and repurpose. Please note that since these logs are natural, the color of each log may vary slightly. Each log is coated in non-toxic & environmentally safe, Fire Retardant Penetrant. However, the candle should not be burned when there is 1/2 inch of wax left and the candle should never be left unattended -Trim your wicks very short (1/4") after each burn and do not burn when you only have 1/2 inch of wax left.
