Our 100% soy wax & fragrances are a healthier alternative to paraffin/petroleum wax candles made with 100% synthetic fragrances. Our candles burn cleaner, produce less soot, and burn evenly. Sometimes after burning our candles, they can look a little different. Rest assure that it is perfectly normal. It's the only indicator that our candles are what we say- 100% all natural soy and this causes their fragrance to last far longer and come across much smoother and crisp.
