Our scented wax melts are all 100% soy wax with no additives or dyes.  They are much more cost efficient than candles, and many people like them because they're much safer than a candle with an open flame.  They provide a wonderful alternative for candle lovers who want to avoid the fire risks in their home, but still love the warmth and fragrance of scented wax products. Wax warmers use a heat source (most in stores these days are electric) to warm up the wax in a dish and release fragrance.  They can last anywhere from 8 hours to 5 days, depending on the scent, size, and company you have purchased them from.  If you like to experience different scents depending on the day and your mood, wax melts are definitely the way to go. I like to pop in something fruity when I'm feeling energetic, and I prefer something sweet and warm when relaxing at home in the evenings.  I can simply pop out the solid wax from the afternoon, keep it in a baggie for next time, and pop in a new melt for a completely different fragrance and feel.
