Katie makes soy candles out of all natural ingredients. Her candles are crafted with 100% soy wax made in the USA. Candles are scented with phthalate-free fragrance & essential oil blends. The 4 oz sizes are made with a cotton wick, while the 8 oz. and 12 oz. sizes are made with an organic, crackling wooden wick (native hardwood). The benefit of a wooden wick (besides that cozy soft crackle) is that it helps to increase the lifetime of the candle since the wood burns at a slower rate. Each candle is hand-poured into recyclable glass jars.
