All of my gel candles are safe when used correctly. Gel Candles burn 3-4 times longer than paraffin wax. I use only the best quality US patented Perneco Gel Wax to provide you with the longest burning, safest gel candles available. All Fragrances are safety and flashpoint tested to ensure a safe even burning candle. Just follow my handy burning instructions located on every candle’s packaging and ENJOY!
