Our candles are handmade using 100% domestically sourced soy wax, free of additives and fillers. We then add only fragrance oils that are safe for skin and inhalation, so they don't have harmful phthalates. The wicks we carefully place in each container are cotton or hemp, they are unbleached and lead free. We use recyclable tins in an effort to keep our carbon footprint down. Did you know soy wax can be washed of with warm soapy water? When you're done burning your Niland Candle, scrape out any remaining wax. Then wash the container with warm soapy water, let dry and fill with your favorite tiny keepsakes.
