Our wick-less candles are so simple to use! All you need is one or two tarts and a wax warmer to heat up and melt these wax tarts. If you’re new to wick-less candles, these are a candle alternative and quite honestly, an inexpensive way to scent your home or office. Robbin Patrice’s wax tarts are GMO Free, petroleum free created from vegetable wax and soybean oil. The throw (distance to which you can smell the fragrance) goes a great distance. They also last weeks!
