The Ceragem Ceratonic Belt is a heating belt made of Ceratonic stones. It can be used on any affected or painful part of your body. Plus, you can heat it up at night and sleep all night with it placed on the painful area. You can apply heat for belly fat, weakness, waist, knees, shoulders, chest pain, fatty liver, and heart blockages. Actually, I bought two belts, one is being used and the other is not being used. It hasn't been used for even a single day, so I want to sell it.
