Thank you for considering our brand for your candle needs.  We make all of our candles at home and use only the best ingredients: 100% Organic Soy Wax, Cotton Wicks, and Phthalate -Free Fragrance Oils, and Pure Essential Oils.  All of our candles burn emitting invisible levels of soot and smoke.  The melted wells are also safe enough that you use them as hot oil moisturizers.
