Should only be used in appropriate wax melt burners. The number one rule is to never leave a in-use burner unattended. If using tealight burner:eak off a segment/heart from your wax melt (depending on your burner size), add a tea light underneath, light the wick. Keep using new tealights until you can no longer smell the scent. If using Sassy Wax Original Warmer - Electric Wax Burner:eak off a segment/heart from your wax melt, add to the bowl in the top of the burner. Press the button on the burner once for a 3 hour burn, twice for a 6 hour burn and 3 times for a 9 hour burn. Your wax melt burner will turn off after the selected time. If you want to turn off early, click the button until all lights are off. If you burn 13g this will be somewhere around approx 12-18 hours of scent in total. Please ensure you don't overfill your wax burner. One or two segment(s) is enough. The intensity of fragrance will depend on your room size, the temperature of the room and amount of wax used. For best results, always close your windows in the room you are burning the wax. Once the wax is spent, use cotton balls/pads to soak up melted/molten wax and then dispose of it accordingly. Do not use wipes and/or cleaning chemicals/products to clean the burner. Do not use metal or sharp objects to clean out wax as this may crack or damage the burner or cause injury. Please check the packaging for allergen advice. Keep away from children.
