How Long Will They Last?Our soy melt cubes will release fragrance for approximately 45-50 hours per bar. Fragrance Description In the heart of the Black Forest, where paths twist and turn, you will find a hauntingly beautiful aroma. The blend of red currant, blackberry, fir tree, cedarwood, juniper, and oakmoss evokes the eerie thrill of wandering through ancient woods, where every rustle hints at hidden secrets. About our Soy Melt CubesOur soy melt cubes are made with Soy Wax, Beeswax and Coconut, and a blend of essential oils and fragrance oils.  We pride ourselves in using fragrance oils that are phthalate free, and are made with high quality plant extracts.  Melt cubes are meant to be used in an oil warmer or a warmer made for wax cubes.  These are typically powered electrically with a light bulb, or by burning a tea light candle.  Simply place 1-2 melt cubes in the top of the warmer, and let them fill your home with fragrance.  These are great if you want to have all the fragrance without the flame!
