Our Jar of Hearts are the best product that pack a decent punch! The jar is filled with individual heart wax melts, each heart lasting approx. 4 - 6 hours! Wax melts are small, scented pieces of wax that are used in wax warmers to release fragrance into the air. They are similar to scented candles, but instead of being burned, they are melted using a wax warmer. Wax melts are made from a combination of soy wax and fragrance oils. To use wax melts, you simply place one or more pieces into the dish of a wax warmer and turn it on. As the wax melts and heats up, it releases the fragrance into the air, providing a long-lasting and aromatic scent throughout your home or office. Wax melts are a popular alternative to traditional candles as they are safer, cleaner, and more economical, as they can be used multiple times.
