Scentsy is a wickless candle company that uses a warmer. The warmer has a lightbulb that melts the wax instead of using any flames. The wax in its liquid form will only get to body temperature. This makes this product safer for both children and pets. The wax comes in a package with 6-8 cubes. Each cube lasts about 80 hours. When the scent is gone, just clean out the top with a paper towel. When you are ready, just pop in a new scent cube and turn the warmer on. There are many different warmers and several sizes including a Plug-in warmer for those smaller spots (ex: bathroom). There are over 80 different scents to choose from. There is also a new warmer and scent of the month, each month Please check out my website for the full product line including room sprays and more. Thank you!
