You don't have to worry about flames if you leave the warmer and wax unattended. Scentsy has more than 50 decorative warmers and more than 80 unique scents to choose from, so you're sure to find several combinations you love! Choose from full-size warmers (which use a 25-watt bulb), medium-size warmers (which use a 20-watt bulb) and Plug-In Warmers (which use a 15-watt bulb). Plug-in warmers are great for small rooms, bathrooms and kitchens. Just plug them into the wall and turn them on. You may even be interested in joining my Scentsy team. The product sells itself. You get to meet great people and earn extra money. Contact me if you are interested.
