Have you ever wanted to have a steady stream of fresh mint filling your room? So did we! That's why we made our own menthol crystals and paired them with our beautiful metallic electric perfume warmer. As the heating device heats up, the crystals will melt, releasing a fresh mint scent into the air. During use, light shines through the woodland-shaped holes of the fireplace 7.3" H x 4.3" W. Pour menthol crystals into the top dish to warm up the fragrance and turn on the lamp to help you breathe better, remove odors, purify the air, create a sweet-smelling ambiance for your room or improve your mood. You can also use any high quality, pure essential oils, wax candies and wax melts to suit your aromatherapy needs. Our menthol crystals were originally developed to create an amazing aromatherapy effect in a sauna, similar to what you would get in a eucalyptus steam room. These all-natural crystals are colorless and clear, and are a natural by-product of steam distilled peppermint essential oil. The most common uses for our menthol crystals are to deodorize a room and create a vapor to ease breathing. You can also use them to help relieve coughs, congestion, flu symptoms, and upper respiratory problems. Many customers report using menthol crystals to soothe sore muscles, help relieve tension headaches, or relax tight neck muscles. Please note: menthol crystals can melt at high temperatures. If you find your crystals have melted in the jar, don't worry! You can still use it. Simply break it (carefully) into small pieces and add them to your wax solvent or warmer as usual.
