Each Elizabeth M candle is hand-poured with all natural soy wax, premium fragrance oil and natural cotton wicks for a clean burn. To keep the process as natural as possible all Elizabeth M candles are made dye-free. Soy wax is made from Soybean oil, an all-natural renewable and biodegradable resource. For best results burn your candle 2-4 hours at a time to assure a proper wax pool and avoid a tunneling effect. The 8 oz and 16 oz tins have raised safety feet to help keep your surfaces cool.
