Scentsy Wickless Candle Plug-In Warmer includes 2 Scentsy Bars (wax). Approximately 5" tall by 3"wide, with on-off switch. These make great gifts for family & friends! Safer than regular candles with a flame (because there is no flame), especially around children and the melted wax will not burn you! Use it as a great smelling night light that you can change scents whenever you feel like it. Great for small areas like bathrooms.
