Madeline Island Candles Purity Unscented Soy Wax Melts (2 Pack) Choose your own scent for the day by adding drops of essential oil to our unscented wax in a wax melter. With unscented wax, the oils burn evenly for longer, more consistent burning, and a more powerful scent. Our soy candles use 100% natural, domestically grown soy wax with cotton wicks. Soy candles are all hand-poured on Madeline Island WI, USA by island residents.
