Scentsy is quite simply the safest way of melting scented candle wax without having to worry about an open flame, soot or smoke. Highly scented wax is melted using a low watt light bulb in a ceramic candle warmer. Each Scentsy wax bar is made of food grade petroleum wax and lasts approximately 80 hours. Scentsy offers a wide variety of scents (over 80!) and a huge number of candle warmers to choose from (over 40 mid, full size and premium warmers plus 20 plug-in warmers).
