Two's Company Shell Filled Scented Candle is a fine bone porcelain wax-filled candleholder with a sea spray scented wax. The candle is 100% soy-based. Soy wax is made from environmentally friendly, renewable resources; whereas classic paraffin wax is made from petroleum and is non-renewable. Soy wax also burns slower than paraffin wax, meaning you get a candle that lasts longer.
