Soy wax burns clean without the black soot and other carsinogens. People with allergies to traditional paraffin candles usually tolerate Soy wax candles. Scented with premium fragrances developed specifically for Soy wax, these candles burn low and slow and have a tremendous scent throw. You won't be disappointed. Burntime for this 314ml jar is approx 70 hours. You've never had a candle SOY good!!!
