Scentsy Candles are flameless and wickless. Decorative Scentsy Warmers use a 25-watt light bulb to heat scented wax. The scent is warmed out of the wax without the harm of lead, chemicals or soot releasing into the air. Scentsy Candle Bars have a burn time (or "warm" time) of up to 80 hours. There are more than 50 unique warmers and over 80 scents to choose from.
